I have a sketch that retrieves data from an nRF wireless module and then transfers it with a GET to a web server for insertion into a MySQL database.
I was getting issue with packet loss and finally troubleshoot it to the ethernet connect>send>disconnect. This appears to take around 295ms, with the nRF bits only taking 5ms extra, This limits me to 3 incoming packets without loss.
With payload header that gives me basically 72 bytes per second of reliable data transmission. That's poor by any standards.
I just wondered if ~300ms is about typical for doing a GET to a web page on the internet?
