About the course
Once our program works correctly we can start focusing on making it faster. There are a number of tools to achieve that, one of them is to make the program do several things at the same time.
In Perl the most natural way to do that is by creating multiple processes using fork.
In this course you'll learn how to use fork to make your code faster. Maybe a lot faster.
