Re: lenovo R60 SMP/APIC_IO woes
:Whoa! 4 minutes! Very cool!
:
:Mucho better! :) :)

:Now .. speculating as to the cause ... could it be that interrupts are only being delivered to
:CPU0 and not CPU1 ? That would explain the roughly 1/2 speed slow down during the test if both
:cpus were alternating running compile processes ..

Nope. Well, yup... but that's normal. When the PIC is used interrupts
are usually only delivered to one cpu. But it wouldn't cause a
slow down. Performance would be about the same.
