Eclipse startup performance - very bad [message #1809273]

Let me start by quoting my comment from year 2014:

Quote:

The "same" workspace in Indigo (3.7.2) SR2 loads in 4 seconds, in Kepler SR2 (4.3.2) in 7 seconds and in Luna (4.4.0) in 10 seconds. All are Java EE bundles.

Now in 2019 I use Version: 2019-03 (4.11.0) and the loading time is ... wait for it... 15 seconds!

That is 3 seconds for the workspaces chooser and 12 seconds until the main window appears. Not counting additional 2-4 seconds until it is actually usable.

Also: now I have a much more powerful computer: 4 cores, over 3GHz, tons of RAM (over 32 GB) and a SSD.

None of the suggestions on that page make any noticeable change:
- disabling antivirus
- disabling plugins startup
- Xverify:none
- latest JDK (12)
etc...

So... did the developers just give up? Buy an even faster PC? Or is there a chance, a trick, to make Eclipse start faster?

Regards,
David

PS: OS is Windows 7, as in 2014

It's hard to say without detailed measurements and knowing more about the state of your workspace. Are editors open on startup? For me, if I open Eclipse and have told it to just use the workspace it used before (no chooser), and that workspace has no open editors, it takes roughly 10 seconds to open, though as you say, the busy cursor takes a few more seconds to go away.

I've done performance tuning on the startup time in the past, and made a few improvements, but many things are just slow to start and much of that is loading all the classes. And over time, of course more and more features are added that require more and bigger classes to be loaded.

This blog seemed interesting:

I extracted freshly from eclipse-jee-2019-03-R-win32-x86_64.zip , then started it, created a new workspace, then closed and opened again and measured the time. From click on the eclipse.exe icon to loaded workspace (showing the welcome screen) it took 13 seconds.
Compared to 4 seconds with Indigo (on slower PC) this is a very big regression.

You might want to retry this test with the Indigo and 2019-06 Platform downloads, just to rule them out. The Java EE bundles that affect startup times aren't the ones that tend to change from release to release.

I downloaded eclipse-jee-indigo-SR2-win32-x86_64.zip and run it , creating a fresh workspace.
Total startup time is 5 seconds. If I add the Xverify:none option, then it is 4 seconds.

eclipse-jee-2019-06-R-win32-x86_64.zip it is 14 seconds.

Yes, you already mentioned that. It's why I directed you to try the Indigo and 2019-06 Platform downloads and see if the differences came from there.

Sorry, I overlooked that.

Are these the correct packages?
- eclipse-SDK-3.7.2-win32-x86_64.zip
- eclipse-SDK-4.12-win32-x86_64.zip

They start in :
4 seconds (3.7.2 with JDK 1.6.0_45)
10 seconds (4.12 with JDK 12.0.1)

I was actually meaning the eclipse-platform downloads that are further down on the same download pages, but the results of the SDK downloads are still useful.
