Poll is slightly faster, but you should prefer poll for other reasons than speed.

In general, B will be faster, but it really depends on details about your protocol. What I usually do is have the thread that created the data check to see if any data is buffered for that connection. If so, it just adds the new data to the buffer. If not, it tries to send the data itself and adds the remainder, if any, to the buffer.

Yes. I forgot the URL to the web page that describes this. For less than 8,000 connections, it doesn't make much difference.
