I am running a few slightly complicated graphics. When these run for a while, it appears that the CPU utilization (for the front-end and back-end) never exceeds 13%.

But when I run a "pure calculation", it goes up to 60% (back-end). The calculation in this case is a LinearSolve[] of a 100-by-100 RandomInteger[] of mx=b.

Is there some setting to make the system use more resources to complete faster when resources are available?

My machine is Win8.1, Mma 10.1, 3.5Ghz, 4Cores, 32GB memory.

No other applications are running on the machine during these tests.

Thanks in advance.
