Subject: Disk performance irregularity in 2.4.x -- another trace
Date: Wed, 25 Jun 2003 15:49:18 -0500 [thread overview]
Message-ID: <v04003a45bb1fb9f4ce1b@[192.168.1.4]> (raw)
To follow up on my previous message, I just caught another instance of my
disk performance irregularity with vmstat. This time the system was
basically "idle".
This trace doesn't show any context switch oddities, so I suspect it was
just some spurious process doing something weird on the last trace.
