RHEL high percentage of processor time from system 5198
Greetings All, I have a dialup debian box that serves as a gateway for my home LAN. I have a firewall-ipmasq script (from the iptables HOWTO...
hey folks, I had this problem with the Ubuntu Hoary upgrade from Warty also. I've filed a bug report twice, but got no answers. I'm...
The disk i-o is actually pretty low ... I really don't think it should be an issue. No other processes are using CPU time (except 0.1% by kjournald). Could be the filesystem... disks aren't close to full yet, but they are regular IDE as far as I can tell. (wouldn't this show up under "i-o wait" and the other values from "top"?)

The Xeons are 2.4 GHz each if I recall correctly, and the FC3 box is 1 Intel P4 3.4 GHz HT.
Unfortunately I cannot stop these processes now, it will be two days or so before they are done. I'll try some very simple tests, e.g., fortran vs. c vs. matlab with no disk i-o, fortran vs. c vs. matlab with heavy disk i-o. I'm including Matlab in there to see how it compares, and I have programs that do the same thing but are written in all three "languages". I'll post back when I find out more information! Thanks for the ideas.

Ben It depends what is going on. I run BOINC projects at nice 19 to gobble up the spare time doing something remotely useful. So whenever a "real" process needs the processor...
