Why Ruby isn't Slow

Ruby, perhaps more than any other dynamic language, has a reputation for being slow. But this doesn't have to be. I've spent the last year building Topaz, a high performance Ruby VM, built on the same technologies that power PyPy. This talk will be an overview of what makes a Ruby VM slow, and how we solved.

Some examples:

* Method dispatch
* Constant lookups
* Allocation of integers, floats, and other "primitives" on the heap
