Alright, so I've been running some numbers on proxy speeds lately trying to set up a solid testing methodology. The problem I keep running into is how some providers claim lightning-fast speeds but turn out to be slow motion when you actually test. If you want a proper test, don't just rely on quick ping or download speeds. I mean, run a real scrape or load a lander from your typical geo and check the actual response time, packet loss, and stability over a couple hours. Anything that's not consistent in this test is a red flag. Beware of bad providers who only show you a flashy speed test result in their reviews or on their dashboard. Those numbers can be rigged, and once you start your campaign you realize it's all smoke and mirrors. I've burned enough budgets chasing false promises, so my rule is always to simulate real use, test with actual traffic, run it for a few hours, and look for dropped connections or spikes. Sometimes those cheap proxies look fast on paper but turn into a lag fest under load, and that's how you lose EPC fast. If anyone's got a solid, objective method, I'm all ears - because I am stuck on how to reliably differentiate between the fakes and the legit high-speed providers.
