Hi,
I'm currently migrating an SVN repository to Git using git-svn (Git
for Windows 1.8.3-preview20130601), and I'm experiencing severe
performance problems with "git svn fetch". Commits to the SVN "trunk"
are fetched very fast (a few seconds or so per SVN revision), but
commits to some branches ("hotfix" branches) are currently taking
about 9 minutes per revision. I fear that the time per these commits
is increasing and that indeed the migration might not be finishable at
all.
For the commits that take such a long time, git-svn always outputs
lots of warnings about ignored SVN cherry-picks, and it tells me it
can't find a revmap for the path being imported. (See [1].)
AFAICS, the offending commits take place on some branches that include
a lot of manually merged ("SVN cherry-picked") revisions. Git-svn
seems to be checking something (though I don't know what) that makes
importing these revisions really slow. And it repeats this for every
revision on these branches with increasing work to do.
Is there anything I can do to speed this up? (I already tried
increasing the --log-window-size to 500, didn't have any effect.)
Thank you, best regards,
Fabian
