Ruby Performance

When Ruby was designed, performance was not a first priority. Instead, we got a great, dynamic language that everyone can use, but Ruby is often criticized for having bad performance. However, performance in today's solutions is crucial, and new Ruby virtual machines are popping up with greater performance than the standard implementation. In addition, these new VMs offer new possibilities in regards to interoperability with e.g. the Java and .NET platforms. We will run through the most important new, exciting developments in the Ruby VM world.
