Linux 2.6.30 Kernel Benchmarks

With the Threaded I/O Tester when using 64MB writes with 32 threads, the latency actually increased when using the Linux 2.6.30-rc7 kernel. The time was worse by 19%!

While the 64MB write latency was higher, the 64MB read time for the Threaded I/O Tester actually improved with the newest kernel. The Linux 2.6.30-rc7 kernel performance was better than Linux 2.6.29 by 30%.

With the Dbench test profile, there was a major jump in performance with the Linux 2.6.30-rc7 kernel! With 12 clients through Dbench, the performance on the 2.6.28 and 2.6.29 kernels was both less than 50MB/s, but with the Linux 2.6.30-rc7 kernel this number jumped to nearly 165MB/s.
