It does not appear here:

Do you compared linux-image-2.6.18-3-xen-amd64 with
linux-image-2.6.18-3-amd64 (on the same machine)?
Should I try 2.6.18-3-xen-vserver-amd64 instead of 2.6.18-3-xen-amd64
(or 2.6.18-4...)?

Hello,
which information is still needed? The problem also occurs with
linux-image-2.6.18-4-xen-amd64.

Hi,
I made the same test on a 32 bit K7 (Athlon 2400+) system: Xen works
very well. My stupid test script (see below) needs with

- the xen kernel 2.6.18-3-xen-k7, but without libc6-xen (stupid, I know)

- the xen kernel 2.6.18-3-xen-k7 and with
Thank you for the fast response.

Severity: important
Booting the xen linux image, the cpu performance is much slower
than with a vanilla kernel (also 2.6.18). A simple shell script
(which compute some numbers, no I/O) needs 60 percent more cpu time
if I am using the xen k
