Windows 8, msysGit. git repack -adf on msysgit/git (best of 3 runs) + nedalloc: 10.5s - nedalloc: 11s git repack -adf on torvalds/linux (best of 3 runs) + nedalloc: 3m 24s - nedalloc: 3m 47s We need to make a decision: drop nedalloc, update nedalloc to later release, patch nedalloc to make it work under MinGW-W64 or disable nedalloc under MinGW-W64 (still leaving it enabled under MinGW). P.S. Waiting for "Resolving deltas" when cloning torvalds/linux is a pain, perhaps someone should run gprof on it. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
