Immutability doesn't always bring performance improvements. Actually,
immutable structures and algorithms that use them tend to have poorer
performances than mutable ones in single threaded situations.
Immutable structures *may* provide a boost in performances in parallel
scenarios, but it's certainly not a foregone conclusion.
Sure, but I was referring to the words of Dick and clearly he's
experiencing some performance improvements _at least in some areas_,
otherwise he wouldn’t have mentioned it. In my mind, I imagine you
improve performance in some parts and make it worse in some areas... but
the balance?
Of course, there's also the reduction (and eventually total eradication)
of deadlock risks.
