Maybe. What version was the "old" PGP? What symmetric cipher did you use
with each program? Perhaps GnuPG used Triple-DES, which is much slower
than the IDEA and CAST algorithms that were the default in older PGP
programs. You can change your kep preferences to use AES, CAST, or some
other speedy cipher with GnuPG.

I assume you eliminated the obvious possibilities for the slowness:
other system activity, file system fragmentation, etc.
