I am extracting the package rate of a receive signal using a rather complex GRC flowgraph, i.e. I am detecting the preamble of a receive signal and generate a clock from here. This clock signal period is within the range of 100us - 1ms.
Toggling GPIOs using the standard GPIO interface for signals this fast is likely not going to be very speedy.

The GR experts will have to answer your other questions.
