I keep tabs of a particular svn repository over many years and run "git svn fetch --all" every few days. So that's the old clone. Since this discussion started, I made a new one with git 2.1.0 patched with the first two patches below, a couple of weeks ago. And I ran 'git svn fetch --all' on both every few days since. I have added a few more patches, so the whole list is the 6 below against 2.1.0. The latest fetch is really strange - the fetch against the new clone took almost twice as long and uses almost twice as much memory, vs against the old. 17 min, 800 MB vs 10 min 400MB. Details below. Maybe this is a performance issue about how the clones were made? 0001-git-svn-only-look-at-the-new-parts-of-svn-mergeinfo.patch 0002-git-svn-only-look-at-the-root-path-for-svn-mergeinfo.patch 0003-git-svn-reduce-check_cherry_pick-cache-overhead.patch 0004-git-svn-cache-only-mergeinfo-revisions.patch 0006-git-svn-clear-global-SVN-pool-between-get_log-invoca.patch 0007-git-svn-remove-mergeinfo-rev-caching.patch (I dropped #5 because it doesn't seem interesting?) <--- $ /usr/bin/time -v git svn fetch --all ...
