First check the log file, if your batch render takes one or two licenses.
Then test a simple scene, just very simple objects, but with a heavy render
tree, e.g. some mixed fractals with high recursion steps and/or increase the AA
to very high samples, anything that makes the render time of your image much
higher. Cause you get 50% if XSI does scene pre-processing and 100% only if
Mental Ray is rendering. This test should confirm if MRay takes only one CPU.
At last you could try to start two render processes on a machine, if the scene
does not have many textures and you don't need much memory, but I would use it
only if the problem is the XSI pre-processing and not MRay, cause it is more
effecive to run one rendering on two CPU's than two renderings on one CPU.
