then stop spouting off uninformed comments about how processes are scheduled

The Rails applications themselves don't need to be altered to run in a multi-core environment.

nor do any other program compiled for that architecture. its the OS that schedules processes, not your userland program. the point is, some programs can be written in a way that makes it easier for the OS to exploit multicore. since ruby is not a functional language, my guess is that it would tend to not help the kernel exploit these resources. but obviously in the worst case, a process can run inside one core and never get the advantages of the rest of the chip architecture. this is about exploiting multicore

Got it?

yes, i get that you know very little about how computers function
