A lot of proxy suppliers have a limit on how many threads are used with the proxies. I don't know much about max thread count but doing a quick google search I get:
"The maximum threads setting specifies the maximum number of simultaneous transactions that Proxy Server can handle."
Transaction, I'm guessing, would be the same as requests.
My question is: how many "requests" does osbot client / osrs have? Or how many threads does osrs require?
