Descryption is faster for new encryption keys. The reason for this is
that GnuPG now uses a much smaller x parameter which is not anymore
about the same size as the prime but about 1.5 times what Wiener
suggests for subgroups (see cipher/elgamal.c#wiener_table). This
makes a huge difference in speed for large keys.
