Ruby was always known to be very slow language. Even when the hype around Rails was on - e.g. around 2006, there was nobody who could make the language fast. The great news is that OracleLabs decided to demonstrate the power of their Truffle framework on Ruby and are working on a fast Ruby implementation. OracleLabs claim that their implementation is ten times faster than the standard Ruby.

I wanted to verify such claim. One thing is being faster in a benchmark, the other thing is to speed up real programs. That is why I decided to write my first Ruby program - the sieve of Eratosthenes and as following video demonstrates, Truffle based Ruby is really faster:
