Re: Long clone time after "done."

I'm using RHEL4. Looks like perf is only available with RHEL6.

heads: 308
tags: 9614

Looking up the tags that way took a very long time by the way. "git
tag | wc -l" was much quicker. I've already pruned a lot of tags to
get to this number as well. The original repository had ~37k tags
since we used to tag every commit with CVS.

All my tags are packed so cat-file doesn't work:
fatal: git cat-file refs/tags/some-tag: bad file
