Arduino - Adafruit 16-channel board, how to properly control all channels with less delay?

I am trying to control a few (8 for now) servo motors using this 16-channel board. I am running to some issues about accuracy, for example, when moving a couple of motors do draw a diagonal line, because of the delay between each servo, each motor…
