Hi, I am considering reverting _rev_list memoization because it
can increases memory usage a lot, which hurting fork() performance on
Linux.
Can you tell me if your original results are under Linux or another
kernel? I may only disable _rev_list memoization under Linux and
leave other OSes unaffected, too.
I've merged some patches from Jakob to improve svn:mergeinfo
performance along with some followup patches to reduce memory
use. However memory bloat is still a problem.
Currently in my "master" branch of git://bogomips.org/git-svn
Eric Wong (4):
git-svn: reduce check_cherry_pick cache overhead
git-svn: cache only mergeinfo revisions
git-svn: clear global SVN pool between get_log invocations
git-svn: remove mergeinfo rev caching
Jakob Stoklund Olesen (2):
git-svn: only look at the new parts of svn:mergeinfo
git-svn: only look at the root path for svn:mergeinfo
