OpenPGP uses CFB mode and thus the encryption cannot be parallelized. However, with a modern Intel processor featuring the AES-NI instructions the encryption is not the bottleneck anymore. Make sure to use GnuPG 2.x with Libgcrypt >= 1.6.0 to employ the AES-NI speedup. You _may_ be able to speed I/O up a little by changing #define IOBUF_BUFFER_SIZE 8192 in gnupg/common/iobuf.c to larger power of 2. Disabling encryption (-z 0) and running a separate gzip will also make use of more that one core. Salam-Shalom, Werner -- Die Gedanken sind frei.
