Question about performance verses IP port

Hey all,
I'm curious if using ports other than 80 would make any difference in the performance of an ethernet shield connected robot?

I made a servo powered device that moves a laser pointer around while I watch on my existing web cam. So far its working great but sometimes the lag is in the 10-14 second range while connected over the internet and in the 5-10 second range while connected over my local network. Sometimes its super responsive, like when the robot is controlled over USB.

I was using external port 8080 forwarded to the arduino web server on port 80.
Would switching them both to, say, port 5000 make any theoretical difference?

Thanks!

as long no network-component (at your provider or your router) doesn't apply QoS-filters that might slow or prioritize port 80 traffic and you don't access the web via a shared proxy configured for port 80 only (so other ports would bypass the proxy), there should'nt be any difference. From the ip-packets point of view all ports are created equal :wink:

Awesome, thanks for the in depth reply! :slight_smile:
