Using XFS instead of EXT3 gives expected results – we get 2350 transactions/sec with… is about 10% overhead. EXT2 filesystem also behaves similar to XFS so it seems to be EXT3 specific performance issue. We do not…

… frequently they benchmark XFS vs ext4, and how much of their recommendation comes from the days of ext2/ext3. So I decided to use sysbench and plot some graphs to compare the O_DIRECT performance of ext4 and XFS… who runs their own benchmarks, and am not religious about filesystems.
