As I told
lhoward, the result will be highly dependent
upon many things. What OS you are on, what compiler you
used, whether you compiled with Perl's I/O or your native
one, so on and so forth. (ObRandomNote: Ilya used to
moan about the fact that Perl was "pessimized" for I/O on
Linux. OTOH Perl is still faster at virtually everything
else...)
I don't doubt for a second that he did that benchmark and
got those numbers. I also don't doubt for a
second that you did your benchmark and got your numbers
as well. The lesson is that this kind of optimization
can only be evaluated if you test against your actual
target environment.
But the advantages in maintainability simply cannot be
disputed. In addition to the bugs I already pointed out,
what happens if someone changes $/ and tries to figure
out why nothing happened?
