Wouldn't you have to do make -j 4 to use 4 cores?  It looks like on the
laptop you're using one 2.5 Ghz core and on the Xen VM you're using one 2.66
Ghz core.

Thank you, that has made a huge difference. Still, I'm concerned with the results now:

laptop (make -j 3) (2 cores)

real    0m16.70s
user    0m26.82s
sys     0m5.50s

virtual server with 4 cores (make -j 5) (4 cores)

real    0m22.36s
user    0m26.24s
sys     0m54.97s


Is this a reasonable expectation with virtualization?
