Investigate higher tick frequency

Updated in 1089307, the control software's clock tick frequency is 10Hz.

It's worth investigating what's preventing us from increasing the frequency to an ideal 100Hz, or the ⅔Hz that it was before the change. I know we experienced sever input latency with a higher frequency and suspect we'll need to profile the application to understand what's going on.
