I have imported with svn2git a SVN Repo. Now I left with the choice how to repack/garbage collect the repo to reduce the size, but I dont want to sacrifice the performance of later git operations. How do I do that?

The homepage of the tool suggests: 

git repack -a -d -f

or should I use a really long depth and window:

git repack -a -d -f --depth=250 --window=250

Does performance of later git operations suffer from these gc decisision?

See this detailed experiment for explanation of the effects of these parameters.

Default values for git gc --aggressive are now 50 and 250 so you can just run git gc --aggressive and rely on it having proper defaults.

  • But how does that influence my later git performance, e.g `git status`. Is it bad to have only one pack? – Gabriel Aug 27 '19 at 11:49
  • `git status` compares files in the work dir with *index*, not with pack(s). I don't have problems with one pack but I have plenty of memory. For memory-constrained systems (like Arduino, Raspberry Pi, etc) it's perhaps better to have a few smaller packs. – phd Aug 27 '19 at 11:56
