Okay.

JMW shows that vectorized was much slower also in Julia (though still both faster than R - but that&#x27;s not difficult).<p>Glad to see Julia is very fast in both cases, though it&#x27;s still somewhat perplexing the extent to which vectorized code is necessarily slower. I&#x27;m thinking that the future of GPU enabled languages will mean vectorized code will be faster, so I prefer languages with a bias towards vectorisation.
