KernelTrap: Benchmarking 2.6

"In a recent posting to the lkml, Kenneth Chen summarized, 'the roller coaster ride continues for the 2.6 kernel on how it measures up in performance using [an] industry standard database transaction processing benchmark. We took a measurement on 2.6.11 and found it is 13% down from the baseline.' The baseline he mentioned was run on a RedHat Enterprise 3 Linux kernel, and compared to the latest 2.6.11, as well as several earlier kernels. In their benchmarks, 2.6.9 performed 6% slower than their baseline in database transaction testing, 2.6.8 performed 23% slower, and 2.6.2 only 1% slower. Kenneth noted that going forward the plan is to benchmark each officially released kernel..."
