What’s the Best Proxy Server Port to Use for Optimal Performance? or How Do I Choose the Right Proxy

Honestly, the best proxy server port depends on your use case. Ports like 8080 and 3128 are popular, but yeah, they get blocked or throttled a lot.

I’ve had luck with 1080 or even 8443—less common but still reliable.

If you’re worried about speed, test a few with a tool like ProxyBench. Some ISPs throttle specific ports, so YMMV.
