The OP said he encrypted to about 50 recipients. With such a small file, the
asymmetric operation will be way more significant in the total time than if the
file were much larger. You seem to be encrypting to only one recipient (you have
a default-recipient?), so the comparison is way off.
Furthermore, you'll need to establish the key size and asym cipher used for the
recipients before you can do a fair comparison. Because a tin-foil hat RSA 16k
key will be a bit more intensive than a 1k DSA key ;).
I use the GNU Privacy Guard (GnuPG) in combination with Enigmail.
You can send me encrypted mail if you want some privacy.
