Subject: KVM performance
Date: Fri, 26 Jan 2007 16:21:07 -0800 [thread overview]
Message-ID: <1169857267.30807.44.camel@localhost.localdomain> (raw)
Hi,
I did some testing of KVM on my woodcrest machine. And I found that
building a 2.6.19 kernel with identical configuration takes 845 sec on a
guest and 210 sec on the host. So the compile is about 4X slower on the
guest :(
The guest ran with 2.6.19 kernel and host ran with a 2.6.20-rc5 kernel.
The guest file image is created with raw format. Wonder if people see
similar performance figure?
Tim
