Subject: [Qemu-devel] qemu-smp guest on monoCPU host: big slowdown
Date: Wed, 04 Jan 2006 13:26:41 +0100	[thread overview]
Message-ID: <1136377601.43bbbf0178301@webmail.alinto.com> (raw)

Hello

I'm trying to use the new -smp option.
host: win2k
guest: linux 2.6.13-SMP

The first sight is a really big slowdown.
with -smp 2, the guest seems to go approximatively to 1/4 speed of a 
monoCPU guest.

I tried to boot with -smp 8, but it was so slow that I abandoned.

Am I doing something wrong? 
Is it unavoidable? Some options to use to compile qemu, or to 
compile the SMP kernel?

Thanks for all informations
