Ext4 is marked stable in Linux v2.6.28, and I have done a very simple test on one disk-partition of my slow laptop, and the numbers look very promising. With default created ext3 disk-partition on my harddisk the 'git checkout -q my-v2.6.25/27' test takes around 20 seconds real time for the best cases. The same test run on a ext4 partition takes around 14 seconds for the best cases. And, since ext4 supports nanosecond timestamps, when I added patch 2/2, the checkout time is much more stable and more close to 14-15 seconds most of the time. Conclusion: for GIT on my laptop the ext4 filesystem is a speedup! >From '/proc/mounts' here is the mount options: /dev/hda10 /home ext3 rw,noatime,errors=continue,data=ordered 0 0 /dev/hda12 /opt2 ext4 rw,noatime,barrier=1,journal_async_commit,data=ordered 0 0 /dev/hda10 is formatted with default (gentoo) ext3 parameters, and the /dev/hda12 is formatted with: /sbin/mkfs -t ext4 -I 256 -G 64 -Oflex_bg,uninit_bg /dev/hda12 Kjetil Barvik (2): fix compile error when USE_NSEC is defined make USE_NSEC work as expected builtin-fetch-pack.c | 4 +- cache.h | 6 ++-- read-cache.c | 70 ++++++++++++++++++++++++++++++++++++++++---------- 3 files changed, 61 insertions(+), 19 deletions(-) -- 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
