RE: [squid-users] Squid Performance (with Polygraph)

I've been testing quite a few combination so for this I had hyperthreading
disabled in the BIOS, and SMP enabled on BSD - so 2 processors. If I enable
hyperthreading its 4.

I understand that squid would favour only one processor, yet with SMP on it
lasts 3x longer. My guess would be that's its because the diskd processes
are able to use more than one processor? Except their cpu usage never goes
over ~3%...

Thanks
Dave

How many processors is reported by the kernel (including hyperthreading)?

Squid is only a single thread, so if you have more than one processor pipe
then Squid will only use one of them.
