[sllug-members]: performance concerns using noapic on a hyper-threaded CPU?

[Marc Christensen]

I was wondering if anyone knows if using noapic on the kernel command 
line will impact performance on a single physical CPU machine that is 
hyper-threaded?

I just upgraded my CPU to one that does hyper-threading and my computer 
won't boot using apic.  So, being the overly performance conscious 
computer geek that I am, I am wondering if setting noapic will impact my 
performance.  OTOH, using noapic vs. not being able to boot is a fairly 
big difference in performance so maybe I shouldn't be worried. :)
