We have some fairly robust hardware we are trying to set up a number of para-virtual servers in a clustered environment and we are seeing huge cpu issues. Specs:

Dell 1950: 8 1u servers
cpu MHz : 2660.038
dual quad cores
32G memory each

Our first virual server was configured to use 8G and 4 cores.

I tried running a quick test by compiling our application, simply running 'time make.' The results were terrible:

real    0m56.79s
user    0m26.53s
sys     0m35.46s

In comparison, my laptop (Intel Core2 Duo CPU @ 2.50GHz, 2G mem):

real    0m42.99s
user    0m29.85s
sys     0m6.47s

We then reconfigured the virtual server to use a single core and the results were almost identical to the 4 core test.

Any insights as to what our problem might be would be greatly appreciated.
