Subject: 64 bit guest much faster ?
Date: Fri, 23 Oct 2009 17:54:12 +0200 [thread overview]
Message-ID: <4AE1D1A4.6050001@pms.ifi.lmu.de> (raw)
Hello,
I have a simple question (sorry I'm a kvm beginner):
Is it right that a 64bit guest (8 CPUs, 16GB) is
much faster than a 32bit guest (8 CPUs, 16GB PAE).
(kvm guest and kvm host are Ubuntu 9.04, 2.6.28-15-server,
kvm 1:84+dfsg-0ubuntu12.3). eg "dpkg-reconfigure initramfs-tools"
runs twice as fast on the 64bit guest.
Thanks
Stefan
