"git help bisect" will give you all the information. You start by saying "git bisect start". Then identify a revision that was fast and say "git bisect good" and then identify a build that is slow and say "git bisect bad". Git will then automatically try checking out different revisions, and then you report to git whether the revision is good or bad. Eventually it can narrow down to a single change that introduced the problem. If the performance issues were introduced slowly, this may not work. (I recently discovered a problem with vinyl control this way, and git bisect worked perfectly and we fixed the bug)
