The Benchmark client was designed to be multithreaded to give a better estimation of server load due to multiple connections at a time. Each thread writes to the out stream and reads from the in stream before terminating. A semaphore limiting the amount of threads was added due to "too many open files" errors.

The performance metric is the amount of connections to the server and back within a time frame. I ran three trials with each server for 60 seconds each trial.


Summarized Output:

Simple Server's number of requests serviced in 60 seconds: 111350, 110379, 105050
MTServer's number of requests serviced in 60 seconds:117777, 120248, 119273

Multithreading makes many copies of a program run without actually making a lot of copies of a program. Therefore, one server can perform as many smaller servers would so no one has to wait for a socket to open.
