Subject: CFQ IO scheduler patch series - AIM7 DBase results on a 16-way IA64
Date: Mon, 30 Apr 2007 07:40:12 -0400 [thread overview]
Message-ID: <4635D59C.4050300@hp.com> (raw)
The results from a single run of an AIM7 DBase load on a 16-way ia64 box
(64GB RAM + 144 FC disks) showed a slight regression (~0.5%) by adding
in this patch. (Graph can be found at
http://free.linux.hp.com/~adb/cfq/cfq_dbase.png ) It is only a single
set of runs, on a single platform, but it is something to keep an eye on
as the regression showed itself across the complete run.
