The small attached script does a nice job of showing animation glitches in the glxgears animation. I have run one set of tests, and will have several more tomorrow. I'm off to a poker game, and would like to let people draw their own conclusions.

Based on just this script as load I would say renice on X isn't a good thing. Based on one small test, I would say that renice of X in conjunction with heavy disk i/o and a single fast scrolling xterm (think kernel compile) seems to slow the raid6 thread measurably. Results late tomorrow, it will be an early and long day :-(

Attachment: glitch1.sh
Description: Bourne shell script
