What Makes JRuby So Great?
A production JRuby environment has fewer moving parts than traditional Ruby environments. This is possible because of the JVM’s support for native operating system threads. Instead of managing dozens of processes, JRuby can use multiple threads of execution to do work in parallel. MRI has threads, but only one thread can execute Ruby code at a time.
