Software limitation, There is a bottle neck with the processor. Why?

I am wondering if this is a problem with cAlgo and cTrader?  It only uses 30% of CPU utilization no matter what? I am using an intel i7 6800 3.4ghz.  There is a bottle neck with the processor. Why?

Software Limitation

Sometimes bottleneck-related performance dips originate from the software itself. In some cases, programs can be built to handle only a finite number of tasks at once so the program won’t utilize any additional CPU or RAM assets even when available. Additionally, a program may not be written to work with multiple CPU streams, thus only utilizing a single core on a multicore processor. These issues are resolved through rewriting and patching software.
