The roller coaster ride continues for the 2.6 kernel on how it measure up in performance using industry standard database transaction processing benchmark. We took a measurement on 2.6.11 and found it is 13% down from the baseline.
We will be taking db benchmark measurements more frequently from now on with latest kernel from kernel.org (and make these measurements on a fixed interval). By doing this, I hope to achieve two things: one is to track base kernel performance on a regular base; secondly, which is more important in my opinion, is to create a better communication flow to the kernel developers and to keep all interested party well informed on the kernel performance for this enterprise workload. With that said, here goes our first data point along with some historical data we have collected so far. 2.6.11 -13% 2.6.9 - 6% 2.6.8 -23% 2.6.2 - 1% baseline (rhel3) The glory detail on the benchmark configuration: 4-way SMP, 1.6 GHz Intel itanium2, 64GB memory, 450 73GB 15k-rpm disks. All experiments were done With exact same hardware and application software, except different kernel versions. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
