R for Windows server
Is hyperthreading on? In that case the maximum is 50% .... Are there two processors? In that case the maximum is 25% ....

I need to run a burdensome simulation. I'm using a Dell PowerEdge 2850, 3.8 Ghz CPU, 2 Gb RAM, Windows server 2003, 32 bit. The task manager indicates that Rgui.exe is using 25% of the CPU speed.
Don't believe the task manager, especially on a machine with hyperthreading.
There is no other process that is slowing down R.
Does anyone know if it's a limitation of R? If so, can I set up the program for the CPU usage like I do for the memory usage? Is there a version of R for servers?
No, R runs at close to 100% of possible on properly configured Windows machines.
