The server probably still processes new connections in a single thread (it did on Unix platforms last time I looked at the code at any rate). So although the CPU load overall is not 100%, once you max out one core, it won't be able to process new connections any faster. That said, the rate you are achieving seems quite low for a modern machine. It would be worthwhile looking to see if it is doing a reverse DNS lookup on the client IP address. After that, try using pstack to see what the accept thread is spending its time on.
