How quickly can I collect data (how fast/what speed will Windmill go)?
Windmill will collect 10 readings per second per channel, up to a maximum of 200 readings per second with 20 channels. When using COMIML or LabIML though, you are limited to 5 readings per second per channel. If you have your sampling interval set much smaller than 0.2 seconds, then Windmill may slow down considerably and only make a couple of readings per minute.
