Note: this is on a different repo from the 'git reflog expire --all' I
reported a bit earlier.
I have a git-svn checkout of a subversion repo which I wanted to compress
as much as possible. 'git gc --aggressive' starts to run fairly well, but
eats more and more memory and gets slower and slower. After it gets to
about 45% or 50% progress slows down noticeably and so far I haven't had
the patience to let it finish (40 minutes is already way too long).
A regular 'git gc' run completes without any problems.
$ du -sh .git/
612M .git/
Special about this repo is that it contains two huge objects [1], which
could maybe be a factor:
size pack SHA
- packages/po/sublevel4/da.po:
495661 4654 801cd6451ece536c0ab41f79e09fc52efdf3361f
- packages/arch/powerpc/quik-installer/debian/po/da.po
149515 1403 83a787b20817dc4d72db052de4055e7a7c9221d7
Below some output from top and of the progress of the command showing the
problem. Check the change in number of compressed objects against the
timestamps from top.
Cheers,
FJP
