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 debian kernel 2.6.18-3-k7 1m9.938s - the xen kernel 2.6.18-3-xen-k7, but without libc6-xen (stupid, I know) 1m34.722s, - the xen kernel 2.6.18-3-xen-k7 and with libc6-xen 1m9.681s. I observed that the performance with 2.6.18-3-xen-amd64 on the Xeon dual core machines is similar bad like 2.6.18-3-xen-k7 without libc6-xen - but where is no tls on 64 bit machines... Here is the absolutely stupid test script #!/bin/bash i=0 while [ $i != $1 ] do i=$((i+1)) done called with argument 3000000. Perhaps remarkable is that the "system" part of the time output is relatively high: real 1m40.895s user 1m26.253s sys 0m14.641s is the result on the xeon dual core machine.
