In more complex cases like heavy event processing with lots of
branching MATLAB JIT is easily defeated (LuaJIT possibly would not do
great either). Couple of years ago we did a WiMAX system level
simulator in MATLAB. Or boy, it was slow.
Finally most of the heavy lifting was done in C-code and MATLAB just
became an IO and configuration shell.


P.S. And you pay through the noise as you go: for each CPU core, for
each toolbox, for updates (via contract) etc.
