In fact, the Linux 2.6.30 kernel was 770% faster than its predecessor was and it remained that way with the Linux 2.6.31 kernel and then regressed only slightly with the Linux 2.6.32 kernel. With the new Linux 2.6.33 kernel, however, the PostgreSQL performance atop the EXT3 file-system has fallen off a cliff. Not only has the PostgreSQL performance lost its gains made during the 2.6.30 development cycle, but also with Linux 2.6.33, it is actually much slower than it was in any of the pre-2.6.30 releases." http://www.phoronix.com/data/img/results/linux_2624_2633/2.png
