My understanding is that what you get with PBR is not necessarily an
increase in speed, but a reduction in the amount of memory space needed
to manipulate the data. If you use regular parameters, there is at any
given time *two* copies of passed variables in memory - the one in the
calling handler, and a new copy that's being examined/manipulated in
the called handler. in PBR, the same variable is being manipulated so
there's no copy being made.
