I've tried doing some quick timing, and if it is a performance regression, it's not a recent one --- or I haven't been able to reproduce what Mel is seeing. I tried the following commands while booted into 3.2, 3.8, and 3.9-rc3 kernels: time git clone ... rm .git/index ; time git reset I did this a number of git repo's; including one that was freshly cloned, and one that had around 3 dozen patches applied via git am (so there were a bunch of loose objects). And I tried doing this on an SSD and a 5400rpm HDD, and I did it with all of the in-memory cache flushed via "git 3 > /proc/sys/vm/drop_caches". The worst case was doing a "time git reset" after deleting the .git/index file after applying all of Kent Overstreet's recent AIO patches that had been sent out for review. It took around 55 seconds, on 3.2, 3.8 and 3.9-rc3. That is pretty horrible, but for me that's the reason why I use SSD's. Mel, how bad is various git commands that you are trying? Have you tried using time to get estimates of how long a git clone or other git operation is taking? - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
