Re: Bug: TortoiseMerge starts very slow under Windows 10 version 1709

[David Balažic via TortoiseSVN]

Hi!

Just an info point, if not posted already:

This is also a problem on Windows 7 (Enterprise SP1 64 bit) , TSVN 1.9.7
TMerge takes 2 seconds to open, for simple text files. During this one CPU 
core is at 100%.

Disabling ribbons (in Settings of TMerge) helps, then it is almost 
instantaneous. Almost.

Regards,

There's no way to fix this in TMerge. At least not without a very ugly hack 
that would lead to a whole lot of other problems.
MS will have a fix available on Jan 30. See also here for more details:

Guys,

It's been over 3 months now since this bug has been reported.  This is a total 
killer on productivity that makes TortoiseMerge almost unusable.  Yes, MS did a 
crappy job of dumping this on you, but you gotta fix this ASAP.

Here is what helped in my case:

1 Disable CFG
2 Disable Ribbons
3 Install fresh tortoise from nightly builds
4 Disable all third-party services. Especially intel and realtek.

All those measures helped only together

Re: Bug: TortoiseMerge starts very slow under Windows 10 version 1709

[ISDVT via TortoiseSVN]

In my company, we have the same problem, and on my computer, using version 
1.9.9 (nightly built), it is quick at the beginning and after some hours work, 
it takes several seconds to open tortoiseMerge, but also other windows like 
changed files dialog for example.
Tortoise is a superb tool, but using it becomes unnerving with this slowness.
Thank-you in advance for finding the solution quickly!

We've had the same problem in our application.

However we discovered that the slow GetPixel/SetPixel calls in 
::UpdateInternalImage(int index) were used only in this case (index == 1) and 
the results of the function weren't even used in our application.

So we skipped the calls in this case completely (if (index == 1)).

CMFCToolBar also used by LocatorBar in TortoiseMerge. And option to turn it 
off (in menu) doesn't work properly.
After restart app, it turned on automaticly.
I tried to totally disable the LocatorBar in the code, but I didn't succeed.

Unfortunately CMFCRibbonStatusBar is tightly coupled and can be replaced easily.

But it seems switching off status bar in TortoiseSVN nightly should
improve performance on Windows 10 with Control Flow Guard enabled.

I set breakpoints on these two functions using GetPixel. And with Ribbons 
enabled, i get this call stack:
TortoiseMerge.exe!MyTool::My_MapBmpTo3dColors(HBITMAP__ * & hBmp, int 
bUseRGBQUAD, unsigned long clrSrc, unsigned long clrDest)
or
TortoiseMerge.exe!MyTool::My_UpdateInternalImage(int nIndex)
followed by

[Inline Frame] TortoiseMerge.exe!CPaneDialog::Create(CWnd *) Line 
46 C++ Symbols loaded.
[Inline Frame] TortoiseMerge.exe!CLocatorBar::Create(CWnd *) Line

TortoiseMerge.exe!CMainFrame::OnCreate(tagCREATESTRUCTW * lpCreateStruct)
[External Code]
TortoiseMerge.exe!CTortoiseMergeApp::InitInstance() Line 543 C++ Symbols

You can easily do the same to track all calls if you apply my patch for a 
while.

It did not help me, i have the slowdown with CFG turned off.
And as far as I know, control flow guard protection works only in 
applications that are compiled to use it.
So the advice to turn it off is a kind of "viral fix". Many people turn it 
off, reboot and see that applications have started to work a little bit 
faster, although this is only due to the fact of rebooting.
The only difference I noticed when disabling CFG, is that Hyper-V stopped 
working.

If you want the old performance back with any application with GetPixel() 
"problem", curse MS and follow the instructions here (first post):

Re: Bug: TortoiseMerge starts very slow under Windows 10 version 1709

[TortoiseSVN on behalf of Ivan Zhakov]

I've checked code and found that calls to
CMFCToolbarImages::UpdateInternalImage() also triggered by
CMFCRibbonStatusBar. I think it should be possible to get rid of this
code by adding CMFCRibbonBaseElement derived class that will use
native ribbon api. I'm going to try this approach today and post
update here.

Hi Yuri,

Thanks for diagnostic session, but I'm unable to decode it without
debug symbols. Could you please post call stack to GetPixel() in
TortoiseMerge when Ribbons are enabled. I'd like to disable usage of
CMFCToolbarImages completely in Ribbon mode.

Re: Bug: TortoiseMerge starts very slow under Windows 10 version 1709

[Yuri Kravchenko via TortoiseSVN]

Yes, i have.
And visually I don't see the difference in the start-up time between using 
ribbons and without them.
Running TortoiseMerge.exe without parameters, with ribbons turned on, takes 
about 10 seconds to display the windows.
There is the diagnostic session, generated by perfomance profiler in VS2017:
http://thmod.com/downloads/Report20171120-1141.diagsession.zip
GetPixel takes 90% of the time.
But with my patch applied, it starts in 1 seconds. And I don't see GetPixel 
calls in profiler log at all.

As far as I know, this slowdown does not happen on every computer. On my 
home laptop, I don't see it (however, I have not yet installed 1709 update 
on it).
But a large number of complaints on completely different configurations 
makes this problem important enough to pay attention to it.

What version did you try? Did you enable ribbons for TortoiseMerge?
The should be fixed in 1.9.99. r28027 or later:
https://sourceforge.net/p/tortoisesvn/code/28025

CMFCRibbonButton is only used for status bar indicators, but they
don't have images so they cannot be reason for slow down.

PS: TortoiseMerge nightly works really fast on my Windows 10 with QHD display.

Re: Bug: TortoiseMerge starts very slow under Windows 10 version 1709

Unfortunately, the profiler does not think so.
You are still using CMFCRibbonButton and CMFCMenuBar classes, which are 
inherited from CMFCToolBar, which uses GetPixel. And maybe several other 
classes also use it.
The problem with GetPixel is also that in the last Windows update, the more 
system uptime, the slower it is. Perhaps this is caused by a leak of system 
resources due to some kind of error in the update.
Therefore, at least one object that uses it, is enough to make the program 
run unacceptably slowly.
But I understand that such a hack is not suitable for public use. I'm 
trying to find another way.

TortoiseSVN 1.9.99 (nightly builds) [1] uses native ribbon framework
instead of MFC, so no delays on TortoiseMerge startup.

Thanks, but I don't like this solution since it requires live-patching - 
virus scanners will go completely bonkers with this and we will have much 
more serious problems than just a slow start...

Re: Bug: TortoiseMerge starts very slow under Windows 10 version 1709

As a workaround it is possible to disable the ribbon in TortoiseMerge: go to 
settings and uncheck "Use Ribbons". TortoiseMerge starts much faster, below 1 
second.

I just updated NVIDIA driver to 388.00 and it is now much faster, but steel not 
as fast as before.

Now using the "diff" command between two simple text files take 9 seconds with 
full CPU load. Before it was 30+ seconds.

It definitively seems to be a graphical issue: when I click on the button on 
the upper left of the window to open the menu, it takes 25 seconds to appear 
with full CPU load.

I already have the last driver from NVIDIA: 387.92 released on Mon Oct 09, 2017

I use a GeForce GT 1030 with one 4K screen on DP, 200% zoom and one 1920x1200 
screen on HDMI with no zoom.

I have updated the display driver for my Nvidia Quadro M4000 to the latest 
version 387.95 using the package 
"387.95-quadro-grid-desktop-notebook-win10-64bit-international-whql".

Unfortunately this did not change much.

Try updating your display driver.
I can see the issue on the PC in my office which has an older driver in 
use, but not on my private PCs and Laptops where I can update the drivers 
myself.
So I think it has something to do with that.

Hi,

Same problem after upgrading to Windows 10 Fall Creator Update.

TortoiseMerge fully uses one CPU core, and it takes about 30 seconds before the 
windows shows up. With Windows up to 10 Creator Update it just took 1 second.

Best regards,
Côme
