Subject [users@httpd] Web server on virtual machine have more CPU utilization
Date Sun, 13 Jan 2013 04:25:34 GMT

I have installed and configured apache web server on virtual machine(VM).
The CPU utilization of apache, while serving client requests is very large
on VM.
When I did the same experiment with physical machine the Utilization is
very small.

The CPU utilization of virtual machine with that of physical machine is in
ratio of  25 : 4 % (approx)  respectively. (For around 3000 requests with
concurrency 200)

Why there is so much difference??.  Is there any way to reduce it??

Thanks in advance.
