They mailed the list about performance issues in git. From what I saw there was relatively little feedback.

I had the impression, and I would not be surprised if they had the impression that the git development community is relatively unconcerned about performance issues on larger repositories.

There have been other reports, which are difficult to keep track of without a bug tracking system, but the ones I know of are:

Poor performance of git status with large number of excluded files and large repositories. Poor performance, and breakage, on repositories with very large numbers of files in them. (Rebase for instance will break if you rebase a commit that contains a *lot* of files.) Poor performance in protocol layer (and other places) with repos with large numbers of refs. (Maybe this is fixed, not sure.)

cheers, Yves
