Hmmm, so even if we ask for the height of line 1 Scintilla lays out the whole 
file, well, I suppose it is necessary since Scintilla styles can have differing 
font sizes.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Colomban Wendling]

OK, took me long enough to work on that one, but please give the branch 
[`startup-speed`](/geany/geany/tree/startup-speed) a spin.

My results, which are the mean average time (measuring 
`document_open_file_full()`) for opening Geany's `src/*.[ch]` (96 C files), 
best out of 3 runs:

1.36 (A) | 1.37 fixed-width (B) | ±1.37.1 (C) | `startup-speed` branch (D)
- | --- | --- | ---
0.048028s | 0.068192s | 0.146446s | 0.048415s
825acb21eabd33390616b224b0454886dc7d6ec2 | 
d9f8cdbad58d09f0c18ca8acccb49209263018f0 patched to use fixed 16px-wide margins 
| d9f8cdbad58d09f0c18ca8acccb49209263018f0 | 
b08ae0fe65c0942dca20281d6841dc83406d8b5e

mean difference (`round(Y * 100 / X)`):
  | A | B | C | D
-- | - | - | - | -
**A** |  100% |   70% |   33% |   99%
**B** |  142% |  100% |   47% |  141%
**C** |  305% |  215% |  100% |  302%
**D** |  101% |   71% |   33% |  100%

As you can see, my branch is ever so slightly slower than 1.36 -- if the 
precision here means anything. I'm not sure why 1.37 with fixed-width margins 
is so much slower than 1.36, maybe a change in Scintilla?  Not sure.

Anyway, the conclusion can be that 1.37 is real slow, about 3 times slower than 
1.36 in my example. My proposed fix is back to 1.36-level speeds, and keeps the 
dynamic margin sizes, so I think it's a win-win, although there's indeed a 
little more code complexity.

Hi, any progress on this issue? Same behavior in Ubuntu 20.04, just compiled 
Geany 1.37.1 and it is way slower than 1.36. This is an up-to-date system, 16GB 
RAM, SSD, 4th gen i3 processor.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

@L--U--P--U--S it pretty much points to the same thing, the slowdowns happen 
when you turn on auto margin things.  

Line number margins are set by Geany to fit the line numbers in a Scintilla 
callback IIRC, so its after Scintilla has loaded and done its thing, which may 
have included laying out at least some of the file, so that layout has to be 
done again after the margin is set since that changes the available page width, 
and that re-layout is the extra time you see.  Not sure how we can fix that 
since it is different for each file because it depends on the number of lines 
in each file and so can't be set until the file is loaded.

The marker margins is the one automated by the patch identified by @andy5995 
and it probably also causes a Scintilla re-layout when its set to anything 
other than Scintillas default value (16 I think).  Hopefully @b4n can identify 
a way of setting it before load since its the same for all files.

Because display and margin stuff was mentioned, I did more testing with the 
view options … with an interesting outcome, I think:

Usually, I have line endings turned off, everything else on.
- [x] Show markers margin
- [x] Show Line Numbers
- [x] Show spaces
- [ ] Show line endings
- [x] Show indentation guides
--> 15s

Ok, everything off. Let's reverse some.

- [ ] Show spaces
- [x] Show line endings
- [ ] Show indentation guides
--> 15s

All using version 1.37.0.
15 files loaded at once via project.
Stopwatch precision.

With 1.36: back to 2s, as described [before](#issuecomment-759335428), with all 
options turned on.

It looks like _markers margin_ (~4-5s) and _Line Numbers_ (2-3s) have an impact 
on the load times. The other view options don't have an impact; or at least not 
a measurable one with my test project size and stopwatch.

Does this tell you something?

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

Ok, I can get the slowdown if I make a project with _line wrap on all files_.

That definitely suggests that its a display issue triggered by the margin width 
thing. Possibly hard to fix if keeping the auto margin width, since the file 
needs to be loaded, which does one layout pass, to get line height, to 
calculate the margin setting, which triggers another layout pass.

Maybe add #2140 back in for you folks who load the whole world in one go with 
wrap on :grin: 

@b4n since all Scintilla widgets have the same font and so line height and so 
margin width, can that be calculated with the first file loaded and set on the 
widget before loading for the other files so they only layout once?

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Colomban Wendling]

OK, thanks to the @andy5995's bisect we now know what's going on, and I see at 
least on one of my machines that undoing most of what that commit does roughly 
halves my loading times as well (I guess I never really noticed because I'm 
used for my usual huge Geany session to be slow enough that I don't attend it, 
and I don't restart Geany often either).

In any case, if all the reports about this slowness come from the same issue, 
then we're on the right tracks: having identified the issue usually accounts 
for at least half the work.  Thanks!

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Thomas Wolf]

Because it is mentioned in the very first post, I suggest to add Georg 
Klingenberg's report to the table:

Reported | OS | Version | GTK | slower
-- | -- | -- | -- | --
[msg02989](https://www.mail-archive.com/users@lists.geany.org/msg02989.html) | 
Windows| 1.36 | ??? | no
[msg02989](https://www.mail-archive.com/users@lists.geany.org/msg02989.html) | 
Windows| 1.37 | ??? | yes untimed

In his 
[reply](https://www.mail-archive.com/users@lists.geany.org/msg02992.html) he 
described the familiar behaviour: not the startup per se is slow, but the load 
time of each file (loaded at startup or later).

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

@L--U--P--U--S thanks for doing that, so at least your problem doesn't seem to 
be GTK major version dependent either.

So summarising the data:

| Reported | OS | Version | GTK | slower |
|-|--|||--|
| https://github.com/geany/geany-osx/issues/20 | OSX | 1.36 | ??? | no |
| https://github.com/geany/geany-osx/issues/20 | OSX | 1.37-2 | ??? | yes 
untimed |
| @L--U--P--U--S | Windows | 1.36 |  GTK 2.24.32, GLib 2.60.6 | no |
| @L--U--P--U--S | Windows | 1.37.1 | GTK 2.24.32, GLib 2.66.2  | yes 5-10 
times |
| #2639 | Windows | 1.36 | ??? | no |
| #2639 | Windows | 1.37.1 | ??? | yes untimed |
| @andy5995 | Linux | 1.36 | GTK 3.24.5, GLib 2.58.3 | no |
| @andy5995 | Linux | 1.37 | GTK 3.24.5, GLib 2.58.3 | yes, 2 times |
| @elextr | Linux | 1.36 | GTK 3.24.20, GLib 2.64.3 | No |
| @elextr | Linux | 1.37 | GTK 3.24.20, GLib 2.64.3 | No |

And to summarise my conclusions from that:

1. For some people 1.37(.1) is measurably slower, but not everyone, seems from 
the reports at https://github.com/geany/geany-osx/issues/20 (OSX) 
@L--U--P--U--S (Windows) and @andy5995 (Linux)  it happens on all platforms.
2. @andy5995 bisected it to 
https://github.com/geany/geany/commit/e42a963d6b4f1b2ef2063e59fc4139a250dfe709 
on Linux
3. but neither @codebrainz nor I see any slowdown on Linux

So maybe there is something in the environment that triggers 
https://github.com/geany/geany/commit/e42a963d6b4f1b2ef2063e59fc4139a250dfe709 
to cause slowdown.  

Because that patch sets the margin width, maybe it triggers Scintilla to 
re-layout each file after opening which is a plausible slowdown, but why does 
it only happen on some systems, or is that patch a furphy, those are the 
questions?

Built a gtk3 version myself using 
https://download.geany.org/geany-1.37.1.tar.gz, 
https://wiki.geany.org/howtos/win32/msys2 (with few adjustments to fix 
configure errors) and my home machine.

Outcome: **absolutely no difference** :(
Identical behaviour and time … as described [before](#issuecomment-759335428).

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

@L--U--P--U--S ummm, ahh, Windows, I missed that, yeah well the windows 
downloads are gtk2 up to 1.37, the intention is to switch to gtk3 before 1.38 
release, but it depends on peoples time availability which is unknown in these 
"interesting" times.  So you would have to build it yourself at the moment.

hmmm, 15 files of a few hundred lines taking 11 secs, on Linux I'm testing with 
approx 120 files taking about 6 secs, some of them being several thousands of 
lines (basically Geany and Scintilla src directories) and not seeing any 
difference between 1.36 and 1.37, but @andy5995 is seeing it on Linux.  I'm not 
on a blindingly fast machine, its 9 years old, but it is from SSD, I wonder if 
there is something about some disks? And windows?  I'm not aware of any big 
changes to how Geany reads files between 1.36 and 1.37.  If I get time I will 
try loading the files off spinny disk.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Thomas Wolf]

> Can you time some of the differences with a stopwatch?

### Procedure
1. randomly opened 15 files (ranging from one to some hundreds of lines in 
size) and save those files as project
2. closed Geany
3. opened Geany (empty editor/file)
4. opened project while looking on stopwatch

Repeated steps 2-4 several times while switching between 1.36 and 1.37(.1) once 
in a while. Always got identical timings (in terms of 1-sec-accuracy).

### Result
- at home (better I/O performance in general)
  - 1.37.1 --> about 11 sec in total
  - 1.36 --> something between 1 and 2 sec
- at work
  - 1.37 --> about 15 sec
  - 1.36 --> something between 1 and 2 sec

### Note
As stated, I always started with an fresh/empty Geany instance. While waiting 
for all the project files to open, the Geany window kind of freezes.

Why "kind of"? The editor stays empty until all files have been opened. I 
cannot see the mouse pointer if it is located on top of the Geany window (can 
see it if moving the pointer sideways on top of another window or desktop), 
**but** the window title gets updated with the file, which is currently loaded 
or was loaded last.

Are there windows installers with gtk3 available for download or do I have do 
compile it myself following [this

Just to note the profiles @andy5995 posted above show most time being spent in 
Pango.

As discussed on IRC 
https://github.com/geany/geany/commit/e42a963d6b4f1b2ef2063e59fc4139a250dfe709 
may cause Scintilla to re-layout stuff, but maybe Pango caching is improving 
it, @andy5995 is on Pango 1.42.4 and I'm on Pango 1.44.7

I've narrowed down the specific commit where this slowdown starts.

https://github.com/geany/geany/commit/e42a963d6b4f1b2ef2063e59fc4139a250dfe709

Which is one commit before the release of 1.37.0

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

I can't measure any material difference (the difference is within the error 
caused by my reaction time) between

```
08:56:28: Geany INFO: Geany 1.37 (git >= 915cf6e8), en_AU.UTF-8
08:56:28: Geany INFO: GTK 3.24.20, GLib 2.64.3
08:56:28: Geany INFO: OS: Linux Mint 20 (ulyana)
```
and

```
08:55:54: Geany INFO: Geany 1.36 (git >= 825acb21), en_AU.UTF-8
08:55:54: Geany INFO: GTK 3.24.20, GLib 2.64.3
```

opening a project with Geanys and Scintilla sources.  

Always be careful what you are comparing is identical, use a copy of the same 
files, but don't use the same actual files between the two geanys or OS caching 
may make the second run faster.

Always measure more than once to avoid any system hiesenwork happening in the 
background affecting the results (your mailer fetching stuff, your browser 
updating the news feed etc).

@L--U--P--U--S Thanks for the work, could you please do comparisons using 
versions built with gtk3.  As 1.37 is the last release that will officially 
support gtk2, any issues it causes are likely not going to be fixed.

@andy5995 your 1.37 debug messages shows its gtk3, can you post your 1.36 debug 
just to reassure me its also gtk3.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Thomas Wolf]

Sorry, my mistake. 1.36 is fast, both in the portable and the non-portable 
version. Don't know what happened that night …

I updated the previous post. Now my observations are consistent with @andy5995 
: All versions are fast versions until and including 1.36. Slowdown starts with 
1.37 and goes on with 1.37.1.

Will do some stopwatch experiments tomorrow.

Having the same issue on Windows 10. Did some testing with different Geany 
versions, different install and file locations and two different machines:

### Geany versions
- 1.37.1 --> slow
- 1.37 --> slow
- 1.36 --> slow
- 1.36 **portable** --> fast
- 1.35 --> fast

Notice the different GLib versions. GTK is identical.

### Slow vs. fast
With "slow" I mean the longer load times for opening (new) files, which I first 
realized after upgrading from 1.35 to 1.37. With "fast" I mean the normal load 
times from 1.35.

As already mentioned, the problem is not the startup time of Geany itself, but 
the time to open a file. This applies to opening a text file from an arbitrary 
location on disk, but also **opening a new and empty file** via `ctrl+n`.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

> The difference for loading 161 files is 13 seconds vs 5.

The 13 secs is 81mS per file average, not tragic, but certainly slower than 
before.

Most likely I'd say is a change in Scintilla that does more work each load.

At one stage Geany used to move the carat from the start of the newly opened 
file to the end, likely causing Scintilla to lay out the whole file, does 
anyone know if thats still happening?

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Andy Alt]

I'm having this issue on GNU/Debian Linux 10. I've been experiencing a 
slow-down when opening projects ever since I rebuilt Geany a couple weeks ago. 
I was using the git version. I checked out 1.37.1 and rebuilt, then 1.37.0, and 
things didn't go back to normal until I checked out 1.36 and rebuilt.

It happens with any project, no matter the number of files. Each file takes 
noticeably longer to load than before. I've included some logs and profiling 
output below.

## Project I loaded for each of the 2 profiles

This is only useful to get an overview of the filetypes I'm loading. As I said 
above, it happens with any project. Most of the files I'm opening are of pretty 
average size.

[Colomban Wendling]

Maybe try simply deactivating the feature (`files.save_config_on_file_change` 
various pref) and see if it helps?   That sounds slightly more trustworthy than 
mtimes, depending on the setup.
Anyway, in theory the code guards against loading the session, but there 
possibly could be something fishy preventing it to work in some situations I 
guess.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[Nick Treleaven]

One thing that changed in 1.37 is saving the config every time a document is 
opened (or closed). Is that behaviour active whilst opening a session? (Just an 
idea)

yep sure, sorry for that, I first thougth that this was a 1.37 only problem and 
that could be related...

i created  #2656 to reference this behavior

Yeah, seems I mixed them up. Sorry.

Does it?  IIUC what "issue exists in 1.36" is totally unrelated and about 
whether or not one can create more than one "untitled" files at once.  @fyah 
@elextr BTW, please don't hijack this issue for unrelated things, open a 
dedicated one :wink:

1.37 for Windows was still GTK2 and since it seems already to happen with 1.36, 
it might have a lot more causes :(.

same behavior without the plugin
the log shows the message about new file beeing created but nothing appears

the timestamps also illustrate the 2sec lag 

in fact I have found the same issue exists in 1.36.
It only occurs when there is no file openned. So if I have a file openned in 
geany, then clicking on new will work as expected.
If I open geany empty, it will start by default with a new file, and in this 
case, clicking on new will not work as expected

Re: [Github-comments] [geany/geany] Slow startup (#2649)

Hi,

looking at ReadMe.Dependencies.Geany.txt

from 1.36:  
file:///var/cache/pacman/pkg/mingw-w64-i686-gtk2-2.24.32-4-any.pkg.tar.xz

from 1.37: 
file:///var/cache/pacman/pkg/mingw-w64-i686-gtk2-2.24.32-6-any.pkg.tar.zst

looking at this file might be the way indeed...

how to tell which of the lib change could be causing the problem ?

Sorry if it's a silly question, it just hit me: which GTK version are we using 
on OSX and Windows for 1.37 and before?  As the default switched to 3.x, do we 
use that?  If 1.37 is the first GTK3 release there, it might very well be that…

Re: [Github-comments] [geany/geany] Slow startup (#2649)

Hello
I can definitely say that I notice the slowness since 1.37

file openning is slower, new file is slower as well

running geany.exe -v it waits before message "Geany: unknown : None (UTF-8)" 
appears

```
GLib-GIO: _g_io_module_get_default: Found default implementation winhttp 
(GWinHttpVfs) for â?~gio-vfsâ?T
Geany: Loaded:   C:\Program Files (x86)\Geany\lib\geany\saveactions.dll 
(Actions d'enregistrement)
Geany: unknown : None (UTF-8)
```

in 1.36 the same output is present, but the load time is much faster

I also notice that in 1.37 it is only possible to create one new document, 
whereas in 1.36 it will create 1 new document each time I click on "new" (which 
is better and expected I think)

Maybe one reproducing the issue could bisect if it happened since 1.36?  Not 
sure how easy bisecting is on Windows/Macos (probably depends on how easy it is 
to build), but that could possibly be a cheap-ish way of figuring this out.

I'm exclusively on Linux, and my startup times always have been fairly slow due 
to my huuuge sessions, so I probably wouldn't have noticed either way :)

Local files on a normal disk or what? What filetypes? One file, many files?

@frlan reported also slowiness on startup. His debug message log indicated the 
startup itself is as fast as expected but opening session files takes from 
100ms to 300ms per file. IIRC he had similar times on Linux und MacOS.

Besides that, I agree with @elextr: this either needs some detailed 
measurements or a good hint what could have changed or since when.

Additionally, on Windows, Geany is always and probably since ever rather slow.

Re: [Github-comments] [geany/geany] Slow startup (#2649)

[elextr]

Information from the OPs of those comments/mails about how slow (numbers, 
"seems" isn't a measure) and how to reproduce might be useful.
