So there are essentially 3 things happening here (From the Java perspective):
* The workspace is searched and for each file/folder a ProjektTreeNode is
created. I tested this step already when introducing the ProjectListManager,
and it worked fine (meaning no visible performance issue) with the Saros
repro. It only use the member() and getType () methods of eclipse, which are
quit fast.
* After that this nodes are transformed into a GSON model. I don't tested this,
as I asummed that this serialisation shouldn't take long. I don't know how big
the actual gson is in that case.
* Last step is calling the update Project models in JS with the GSON. This
should also trigger the rendering.
Any Ideas Basti what can cause this on js side?
Ps: You right the scrolling issue is certainly not 'small',from a user point of
view. What I actually meant is, that this is easy to fix, since this is
probably done via css.
Pss: The shell don't allow me to resize it. This is also a 'small' issue (But
on java side).

2*(100/8) = 25% CPU consumption on my machine.
Anyway the CPU consumption should always be < 1% (on ONE core) unless something
expensive is calculated for a very short amount of time.
This is still a small plugin and not a full blown next gen application :P
I already noticed that the browser engine adds about 50 - 150 MB to the JVM
memory usage which isn't that great but still acceptable, but NOT over 700 MB
for a single wizard.
And the "small" issue you found (I forgot to mention it) isn't that small.
After you selected the files you have to find the buttons again ...
Also the headline is not visible anymore if you start scrolling.
Last but not least the font size and icons are a little bit to large.
PS: I got a bunch of npm errors when I tried to "compile" this on my Windows
machine.
At least a hint in the description would be helpful. I managed to compile the
stuff after trying it for 2 hours when I finally
just run:
npm install (in the html directory)
before running npm run build
as this npm stuff was always unable to find the required dependencies in the
default installation directory.

I have the same problems Stefan. I tested it with our Saros repository with all
projects in my workspace (13 k files), and it took about 20 sec and freeze the
whole JAVA machine the projects where rendered. My CPU usage wasn't that high
(about 40%), but it also load until I closed the wizard. The memorie usage was
about 1.2GB, so there is a correlation between workspace size and memory usage
for sure.
Once finished, the projects where all expanded (open to the last node). I
assume that this might be the reason why this takes so long. The browser
renders 10.000 files with 10.000 check boxes and 10.000 pictures at once. This
might cause the trouble, but I am not sure yet, the JSON serialization
shouldn't be that big. And this don't explain why the CPU is still working,
after everything is rendered.
Btw. I found a small issue with the scrolling see:

I would report my experience if only I had some.
I tried to enable the HTML GUI [1], but the view remains empty.
These warnings might be related, but I'm far from sure:

Basti? Matthias?
I had the same problem on my Laptop, but it works fine on my PC.
I am not sure, but you might need to manual copy the "bundle.js" from
"html\bundle\bundle.js" to "html\dist\bundle\bundle.js"
and the two html files into dist as well. The folder should look like this:

Subject: [DPP-Devel] HTML UI Plugin performance issues !
Hi,
I just simulated an average developer IDE workspace (approx. 10k files)
When I open the start session wizard the result is something like:
Memory usage is about 1.5 GB (with a peak of 2.4 GB)
For almost 1 minute 2 of my 8 CPU dies are 100% load and I am unable to
select anything.
After that minute the CPU load is still about 100% load for 1 CPU die
(this also happens with just a single Saros Project in the workspace <
1000 files).
The CPU load remains until I close the wizard.
Can anyone confirm the same behavior on her/his working machine ?
I have the same problems, I testes our Saros project (which is not quite that
big) but it took about 20 sec and freeze the whole JAVA untill the projects
where rendered.
The Projects where all expanded (open to the last node) at the start. I assume
that this might be the reason why this takes so long. If the browser renders
10k o the side tryes to show a list 10k files at start (and 10 checkboxes)
But I am not sure. I found btw. a small issue with the scrolling see:
