Does Tyk gateway have a way to report the time from request received to first byte of response available? We are looking at evaluating performance of various gateways and are trying to eliminate network variabilities.
It does not, however, the latency count in the log browser and analytics starts from after the gateway has completed processing the request (all middleware executed) to the request having been response having been received by the proxy.
You might be able to use that as a baseline and subtract it from the total to get processing time.
