Linux 2.6.32 Kernel Benchmarks

With 8GB file writes, there was only a small performance drop due to the EXT4 change as measured by IOzone.

Again, with PostMark being a disk bound test, its performance also dropped under the Linux 2.6.32 kernel.

The NASA NAS Parallel Benchmarks started running a lot faster with the Linux 2.6.31 kernel and this speed boost was carried forward with the Linux 2.6.32 kernel but not to any greater magnitude.

While there are just nine test results shown in this article, we have been running more Linux 2.6.32 kernel tests on other systems and with more test profiles. Besides the performance drops when using EXT4 and then a few encoding improvements, we have not encountered many performance-related changes with the Linux 2.6.32 kernel.
