Actually, I am running BOINC that has two setiathome and two
climateprediction running. Luckily at nice level 19. When it really gets
hairy is when I populate an IBM DB2 UDB V8.1.7 database which runs over a
dozen server processes at once. Then the load average can exceed 10. But
the BOINC stuff tends to get out of the way at nice 19.
The BOINC stuff screws up the processor caches, though, and makes the
database slow down a lot, even though, nominally, it gets all the
processor time it wants. But it does not get cache hit ratio it needs, so
the disk IO goes at about half speed or a little less. With BOINC turned
off, I get about 12 Megabytes/second to the hard drives, but it drops to
around 4 when BOINC is running those applications, even though they are at
