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

"What's the Best Way to Check Proxies for Speed and Reliability?"

Hey everyone,
I’ve been trying to check proxies for a project, but some are super slow or just don’t work. What’s your go-to method to test them properly?

Do you use tools like ProxyChecker or just ping them manually? Also, how do you avoid the ones that fail when you actually need them?

Kinda frustrating when they seem fine at first but die when you check proxies under real use. Any tips or tools you swear by?

Thanks in advance!
