Default mPrime doesn't use 100% of CPU-Power

Hello,
I run mprime on a Debian-Server with two Intel XEON Singel-Core CPUs in it. The problem is that mprime only use about 30% of the whole CPU-Ressources (the System Monitor says so). What can I do to increase the CPU-Usage of mprime.

Thanks for Help.

Mprime runs at the lowest priority. Anything else running (its a server) will get the cpu first. Particularly if it is a virtual server then you shouldn't really run mprime at all.

Thanks for the answer,
no it's not a virtual server (strictly speaking it's a server used as a normal PC). I set the Priority for mprime to 10 (maximum) but can't get 100% CPU-Usage.
thanks for help.

How are you measuring the cpu time? Many of the linux utilities have trouble with multi-threaded measuring like mprime. "top" for instance doesn't see the threads by default, you must use the "H" command. Many current versions of top also have a bug in the overall cpu usage that over reports null job time.

I hope this is not a corporate network server.

How did you set up mprime - how many worker threads, any helper threads?
