Subject: i/o benchmarks on 2.5.70* kernels
Date: Tue, 17 Jun 2003 01:32:32 -0400 [thread overview]
Message-ID: <20030617053232.GA6218@rushmore> (raw)
Some benchmarks on 2.5.70* kernels. Hardware is quad P3 xeon
with 3.75 GB ram. For some workloads, -mm has higher numbers
than 2.5.70, for others, 2.5.70 is better. Overall, 2.5.70
seems to give more balanced results on these benchmarks.
AIM7 dbase seems to have an inverse relation to AIM7 fserver.
2.5.70-mm8 was highest at AIM7 dbase, and lowest at AIM7 fserver.
2.5.70-mm6 was the opposite. mm6 was highest for fserver, and
lowest for dbase.
