Multithreading Tips

The key to effectively utilizing multithreading is to think concurrently rather than serially. For example, when you have two subsystems within a program that can execute concurrently, make them into individual threads. A word of caution is in order, however. If you create too many threads, you can actually degrade the performance of your program rather than enhance it. Remember, there is some overhead associated with context switching. If you create too many threads, more CPU time will be spent changing contexts than in executing your program!
