If I don't set wsoNoReceiveLoop, then AsyncReceive loops continually calling my OnDataAvailable event. This would be fine if winsock did not put more FD_Read messages in the queue when I don't receive all the data. The problem I'm facing is that on very large transfers, winsock is flooding the queue with these FD_Read messages which produce extra and pointless calls to OnDataAvailable. This is what I'm trying to correct. So, the way I see it, I either have to set wsoNoReceiveLoop and let each FD_Read message produce a single call to my OnDataAvailable event, or I need to let AsyncRecieve loop and somehow tell winsock to not produce the extra FD_Read messages. What produces the fastest transfers and how would I set it up? >> All in all, speed is my main interest here.

I think you misunderstand me. My OnDataAvailable event is calling Receive to read in the data and then that data is processed. The only way I can process it is to read it in. I'm not saving this data to a file on the hard drive or anything. So, I don't know what you mean by "move the data directly where it belongs".
