so i see another proxy auth thread. everyone's got an opinion, zero data. typical. most 'experts' are just repackaging public data and selling it as insight. i just finished a week of testing with three major providers, rotating and residential. the verdict on speed? it doesn't matter. the difference between whitelisted ips and user
ass auth for raw bandwidth is under 2% in my logs. you're optimizing for the wrong thing. the real cost is in the setup time and security failures. had a user
ass pool leak cuz of a script error, got half my ips banned. that's a 48-hour delay and a $300 loss while i rotated the pool. stop caring about the 50ms latency myth. care about which method your scraping tool or bot actually handles without exploding. my data says if you're running automated systems at scale, ip whitelist is a management nightmare that costs more in human hours. if you're a solo guy testing stuff, sure, whitelist your home ip. but if you're moving data, the supposed 'overhead' of user
ass is cheaper than your time. i'll believe anyone's different opinion when i see the csv.
