Computer Benchmarks

Recently we worked on a Java benchmark program to measure the relative speeds of our computers.  The program finds prime numbers, and will print out how many milliseconds were required to find the millionth prime.

We all have a good idea about how fast our personal computers are, but it’s less obvious how consumer machines compare to our robot’s cRIO processor or to external processors like the Raspberry Pi.

    I added my results from running on my laptop. It’s the I5 laptop (2nd row).
