I still dont get the drift about Ruby being fast enough. Ruby is slower then CPython, PyPy, Lua, LuaJit, and literally majority of other popular dynamic scripting languages.

The argument that keeps being throwing up is that It is fast enough for most ( actually only for Rails related ) things and is mostly limited by SQL, but that is like saying my Toyota Prius is fast enough since the high way speed is limited anyway.

I meant most of the complain aren't really about Ruby getting LuaJit speed ( is that even possible? ) or JS V8 engine. Just at least it is on par with Python ( not talking about PyPy either )
