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??

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.
