| |
I have noticed that processes tend to ping-ping between the two virtual CPUs in my Hyperthreaded P4 machine (kernel 2.4.20). I know this would be bad on true SMP systems, but does it have any impact with Hyperthread CPUs? Should I be worried?
Also, hardware interrupts all seem to be going to the first virtual CPU. I assume this is intentional.
