I've switched to btrfs recently. It seems btrfs performs very poor with large directory entry compared to ext4. With ext4, I think I didn't observe much performance drop, but btrfs drops performance a _lot_ with large directory entry. I didn't expect this. It seems I need ext4 (or reiser4/reiserfs/xfs) Regards, -- Yasuo Ohgaki yohg...@ohgaki.net
