BTW, you might be violating Linode's Terms of Service, depending on their interpretation of it: http://www.linode.com/tos.cfm "Prohibited Usage You agree that any of the below activities are considered prohibited usage and will result in immediate account suspension or cancellation without a refund and the possibility that Linode.com will impose fees; and/or pursue civil remedies without providing advance notice. Misuse of System Resources: Intentional misuse of system resources, including but not limited to employing programs that consume excessive network capacity, CPU cycles, or disk IO." You could want to inquire with them to make sure they're OK with this sort of use. Also, you could want to check the logical CPU count as seen from your Xen VM: grep -c ^processor /proc/cpuinfo This will probably print 4 or 8. You need to adjust the number of processes accordingly.
