Efficiency of Network Tables

[cjl2625]

I've recently been a bit unhappy with my teleop main loop running kind of slow. Without any wait/sleep added in, I think each iteration takes around 50-70 ms, and sometimes starves Robot Drive (the "loop is not running fast enough" errors).

This year I've also been using a ton of variables in network tables, one for basically every constant on the robot. So that means maybe 50 network tables calls for each iteration of teleop.

When trying to figure out why the loop is slow, I considered that maybe retrieving these values is kind of slow, if it has to deal with things over the network. Could this actually be the case, or is the loop slowness probably caused by something else?
