What's the Best Way to Check Proxies for Speed and Reliability? or How Do You Check Proxies to Ensure

For speed, I use ProxyBench. It’s lightweight and gives you avg. response times.

But reliability? That’s tricky. I test proxies with 3-5 different sites (Google, Twitter, etc.) because some work on one but fail on others.

Also, keep a backup list. Even the best proxies can randomly die mid-session.
