Reproducible: Always

Steps to Reproduce:
Open synchronize view. (In my case I was trying to sync up with testng https://github.com/cbeust/testng.git)
Comment 1 Ilya Ivanov CLA 2010-12-19 06:01:15 EST 
Sync View seems to be very inefficient with large repositories. I can be worng, but looks like it loads ALL change sets from repository into memory and executes comparison one by one to find changed files.

Our repository is ~900 Mb and contains about more than 20 000 change sets. 
Sync View gobbled 1.3 Gb of phisical memory and Eclipse crashed with out of memory error.
Comment 2 Chris Aniszczyk CLA 2011-02-03 17:22:36 EST 
Does this still apply?
Comment 3 Ilya Ivanov CLA 2011-02-03 17:32:17 EST 
Well... For our repository it doesn't produce OOM anymore, but still grabs a lot of memory (for some branches > 1Gb). And such Synchronization Eclipse slows down dramatically. So still needs some optimization IMHO.
However improvemens are great! In most cases Sync View is usable :)
Comment 4 Nikolay Metchev CLA 2011-02-04 04:48:56 EST 
It's happening for me as well...
Comment 5 Paweł CLA 2011-04-13 13:32:36 EDT 
It's still serious problem. 
Even if extend eclipse -Xmx, Eclipse after succesful synchronization slows down dramatically....
Comment 6 Paweł CLA 2011-04-14 15:21:22 EDT 
I'd like add something more.
I have over 4000 files in 130 projects.
EGit crash (with OOM) everytime I start syncronize.
I use Eclipse Helios 64bit with 3GB Ram (-Xmx3000m). Java 1.6.024(64).
I don't know for sure, but it looks that problem occured after I installed JBoss Tools pack...

Also see bug 352282.
Comment 8 Matthias Sohn CLA 2011-08-16 10:17:22 EDT 
When reviewing and testing [1] (which improves performance for "Workspace Model" sync dramatically) I did some heap dump analysis and found that the Synchronize View currently has a quite inefficient implementation eating a lot of memory to support the "Git Changeset Model" mode [2]. This was also confirmed by Dariusz.

Comment 9 Dariusz Luksza CLA 2011-11-04 05:17:01 EDT 
This should be fixed by change http://egit.eclipse.org/r/#change,4150
Comment 10 Robin Stocker CLA 2013-03-22 06:16:48 EDT 
See bug 396209, where a problem with OOM was fixed for EGit 2.3. Please reopen if the problem still persists.
