My first guess would be that you've saturated one core. 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.
