ReceiveCommits' "Validate that the new commits are connected" logic uses TOPO REVERSE sorting, which forces JGit to traverse the entire project history in order to compute the results. This is slow, so slow that it takes 45 seconds to push a new change to the linux-2.6 repository.

If pushing to refs/changes/ which takes even higher time, sometimes more than 3 minutes. But if having change-id line and pushing to refs/for which is faster.
Why not replace jgit or optimize it?

Is the push performance still an issue for you guys? 

Performance Fix: Minimize number of advertisedHaves

...solved most of our push performance issues.

There have been a few JGit fixes too, which should affect the performance in a positive way.
