Subject: About IO-APIC - General question
Date: Tue, 16 Apr 2002 08:25:26 +0200 [thread overview]
Message-ID: <3CBBC3D6.1947D011@phys.uni-paderborn.de> (raw)
Hello,
from how I understood APIC it purpose on an SMP machine is to give all
processors the possibility to handle interrupts instead of one processor
responsible for them. So when running two jobs on an SMP machine a
non-working IO-APIC would turn into a performance disadvantage. Do I get
this right ? If yes, does anybody have a clue, how much difference this
could make when running IO-intensive programms ? single or two digit
percentages ?
Thanks
Pete
