I am learning how to use Threads. I looked for an example code in Start / Programming / Example: Task Model and Multithreaded Programming. I found a MandelBrot code, which I was able to change a value in the If -then statement to run in Threads or no Threads mode. I added a time() function to get a sense of the execution time. The results are about 140s with Threads and 91s with no Threads. I would have thought that the execution time would be smaller in the Threads mode than in the no Threads mode. Did I assume incorrectly that I was creating a Threads and no Threads situations by modifying the if-then statement? Or is this not good example? Here is the code:
