Linux Disk Utilization, Pt. 2

Previously I mentioned some issues I had been having on Kubuntu Feisty Fawn with disk utilization seemingly caused by unflushed disk buffers. I alluded to believing that my “laptop-mode.conf” parameters were at fault.

With my recent upgrade of that same laptop to Kubuntu Gutsy Gibbon, I kept the laptop-mode.conf file a bit closer to the maintaner’s version. There are some changes to the “dirty-writeback-centiseconds” and the “dirty-background-ratio” values from what I posted, and my issue seems to have gone away. I’ve been able to go back to running my Windows 2003 SBS server with a Centrify DirectControl lab environment and a RHEL 4 Oracle 10g server attached at the same time.

The configuration files that work MUCH better are attached here:

laptop-mode.conf

cpufreqd.conf
