Out of boredom I wrote a trivial progam to calculate the Fibonacci sequence. After testing a large interger package I found I was able to generate numbers with thousands of digits no problem.
After several revisions I have leveraged it into a brutal benchmark for testing the CPU and RAM as well as how fast your terminal window is.
I hope you like my 2 days of work, it was fun to see it go.
I have updated the program, I noticed my like was not working, I am going to check it again, after suggesting my new version is now available.
