deds,
i cant distinguish right now because its an apple to orange comparison
(eg. does time utility used for every platform is the same source code? the
same perl version?) but the benchmark results are valid only for
exponentation versus bitwise shift operation relative to software, hardware
and architecture used per platform...
but you can easily and fairly benchmark it by using the same perl
version and time source code by compiling them with the same compiler
optimization switches.
furthermore, there are lots of factors to be considered like having
multiple processes running, does this platform have equal time sharing or
fair scheduling to every process? or this platform favors more cpu cycles to
those processes having an intensive i/o like disk i/o, network i/o, etc than
less aggressive processes that doing only arithmethic or memory i/o which
causes the scheduler delays its schedule time? that causes this platform is
better to other platform for this operation only? and badly to other
operations?
well its up to you to find out which platform is best suited for your
needs :-> that is why im having multiple operating system on my pc to find
out their strong and weak points :->
