Subject: Re: OFFTOPIC: Regarding NT vs Linux

Win/NT SMP sucks. C't (a german magazine tested SMP boxes) found, that
it doesn't scale very much, because it seems that interrupts are done
only on one processor. Linux 2.0/SMP sucks probably even more :(, as it
has a global spin lock :(((((

I was under the impression (from reading on the smp list) that NT 4.0 spread
the interrupts over the CPU's?

I was meaning to ask... Does Linux do this for all architectures? (I quick
look to me and it looks like interrupts on the x86 are handled by only one
processor?)

P.S. /proc/interrupts would be much kewler if the information was per cpu.
