I think idprio has a good chance of working. Thanks. Load does not tell you a whole lot about performance if processes are prioritized appropriately. Who cares if setiathome is waiting for processor cycles (adding to load), but not taking any time away from processes in the "foreground" (not really impacting CPU usage of work-related stuff)? Just because your load is always >1 when setiathome is quietly waiting to take otherwise unused CPU cycles does not mean other processes are losing any. That all said, I do kill setiathome during work hours (on work machines). However, it has nothing to do with CPU usage. setiathome eats about 14 MB of memory. On my 64 MB RAM PC here at work, that's enough to cause some swapping, and _that_ can hit performance. -- Crist J.
