What's it waiting for? Aug. 24th, 2004 05:52 pm
Is there any way of finding out from the unix (ok, linux) command line whether processes are CPU-bound or disk-bound? Or which is the major cause of (uptime-style) load on a box?

I can't really answer the question directly -- but I can say I had major problems with processes slowing down and acting as if the CPU was taking a huge hit (when it wasn't) when I was running a kernel with UDMA misconfigured. [I still get the same symptoms when copying to my mp3 player.]

Doubt that will help, but you never know.
