Ruby.exe only using 25% CPU resources

When trying to run an intensive Ruby method, I noticed it's only using 25% of the CPU resources while 70% sits idle. Is there any way to configure this to use more? I'm on Windows 7, ruby 2.0.0

You probably have 4 CPU cores. You're running 1 Ruby process. 1 Ruby process = 1 thread = can use max 1 CPU core. The MRI (default) implementation of Ruby currently cannot run more than 1 thread in parallel. For that, you may want to try JRuby or some other implementation like Rubinius that allows parallel threads. I'm guessing you'll need to learn a bit about multi-threading to understand this wholly, start by reading some basic tutorials and then questions like "Does ruby have real multithreading?".

When the process is running, go to the task manager, right click on the program, click "go to process," right click on the process, go to select priority, and check off "high."

Important: never set application to "realtime" it may cause several problems.
