Two trivial Qs, plz

Q1. Is "print" command the slow one?
I use running long (trivial) codes and
sometimes print a lot of intermediate results (just to keep tracking the run).
And it seems that this make program rather slower? Is it so?

Q2. I use both "old":
                  GP/PARI CALCULATOR Version 2.3.4 (released)

           i686 running cygwin (ix86/GMP-4.2.1 kernel) 32-bit version
 compiled: Jul 12 2008, gcc-3.4.4 (cygming special, gdc 0.12, using dmd 0.125)
                (readline v5.2 enabled, extended help available)

and "new":

GP/PARI CALCULATOR Version 2.5.3 (released)
           i686 running mingw (ix86/GMP-5.0.1 kernel) 32-bit version
                    compiled: Oct  3 2012, gcc-4.6.3 (GCC)
               (readline not compiled in, extended help enabled)

for long (trivial and boring) caculations (mainly with isprime() ).

It seems that "new" version is slightly (not 2 times?) faster than the old one.
Is it so?


PS I use Windows 7 Ultimate in case it matters.
