Is there any alternative to the standard GPIO UHD interface, that allows me the desired speed and is this issue I see related to gnuradio and its scheduler or rather to the UHD API for the GPIOs?

Toggling GPIOs using the standard GPIO interface for signals this fast is likely not going to be very speedy.
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.
The GR experts will have to answer your other questions.
