For Web server implementations, there are 4 main schemes: process-per-request (PPR), thread-per-request (TPR), worker thread pool (WTP), and worker thread pool with buffers (WTPB). This paper compares performance of the schemes in response time point of view. WTPB shows the best performance. The appropriate number of worker threads for WTPB depends on the request service time. For short requests, the number can be very small. But for longer requests, it is about 1/6 of the number of simultaneous connections.
