It would be great if we could set how long to wait after a proxy has been used before it can be used again. If you wait 30-45 seconds between each query per proxy you can pretty much scrape Google indefinitely without proxy ban (with dedicated/private proxies). So to be able to control this would really enhance the software. Thanks!
After review of code I can confirm that use Max threads per proxy + Request delay(in parsers settings) is suitable for this case It's work like this: lock proxy for thread wait some time before do request release proxy lock
