Okay so I've been testing backconnect proxies for a month now trying to get consistent results and keep my head from exploding. I used three providers, BrightData, Smartproxy, and some no-name shop. The numbers are telling. BrightData gave me 97 percent uptime, but speed was sometimes spotty dropping below 1 second ping during peak hours. Smartproxy was a bit faster on average around 800ms but had a couple of outages a week. The no-name provider? Total chaos. Downtime, slow speeds, and constant IP blocks. My main concern is the backconnect rotation. On BrightData I set it to rotate every 2 minutes, and it worked decently but sometimes I'd get multiple requests from the same IP within seconds which is no good for anti-detection. Smartproxy was better with their rotation but still had overlaps. Results? I was able to scrape 2000 pages a day with BrightData without getting banned, but only if I rotated properly and stayed below the threshold. With Smartproxy I had to slow down a lot more, and the no-name shop was useless. If you're considering backconnect, stick with legit providers, watch your rotation intervals, and don't expect miracle speeds. They work but only if you manage them right.
