Thank you for that explanation! Does the transaction regarding the GPIO states use the SFP+ ports or the management connection?
I will go for the raw c++ application and come back to the list ASAP.
Thank you all for your answers! Von: Marcus D. Leech <patchvonbraun@gmail.com>

Every GPIO state transition requires a transaction across your network interface, and then into the FPGA GPIO logic. That's the absolute upper limit on toggling the GPIOs from the host. You can test how fast you can make this go with a "raw" UHD C++ program. Once you've established how fast it can potentially go, then you start evaluating how to approach this latency with GR. Right now, the waters are very muddy, and I am not the one to comment on GR latencies, etc.
