Re: [jgit-dev] [egit-dev] Counting Objects taking long in current master

2012/11/5 Markus Duft <markus.duft@xxxxxxxxxx>

Since a while now, we have the problem that pushing to Gerrit takes very long. It takes up to 5 minutes for the "Counting Objects..." step when pushing. The Problem can be avoided when fetching from upstream immediately before pushing - then the counting objects is done in a millisecond...

We upgraded Gerrit from to 2.4.2 while at the same time upgrading JGit/EGit to the current master version.

Matthias suggested to create a thread dump and ask for help here. The dump is attached, anybody any ideas? Pointers in which direction i could continue searching would be great too :)

I had a look into the stack trace, the only thread related to jgit/egit is the "main" thread and it's in runnable state so nothing unusual on the client side. Could you capture a couple of thread dumps on both egit and gerrit side while the slow push is underway ? 

If we have multiple thread dumps we can see which parts of the thread dump are moving over time.

Tools like Samurai [1] make it easier to analyze thread dumps.
