Alright so I see people posting these proxy speed test results all the time and honestly they're mostly useless. Everyone just runs a quick ping or a basic curl command and calls it a day. The numbers look good but then you actually try to scrape something and your script times out. It's because they're not testing under real load. I went back and integrated my testing directly into Scrapebox, since that's what I use for the heavy lifting anyway. The key is to test with actual concurrent requests, not just one at a time. I set up a custom harvest list of 500 URLs on a test server, then ran it through different proxy providers with Scrapebox's multi-threading cranked up to 50 threads. You get the real metrics - average time per successful request, total failures from timeouts, not just raw bandwidth speed. The data tells a totally different story than those generic ping tests. One provider had great ping but failed on 40% of requests under concurrency because their nodes were overloaded. Another was slower per request but rock solid with zero failures, which is way more valuable for actual work. My advice is stop using standalone tools for this and bake your test into whatever you're actually going to use the proxies for.
