The keylength does not matter for large files. Only the performance
of the symmetric cipher algorithm counts. It depends on the recipients
preference which algorithm is chosen, to get more reliable numbers you
should use "gpg -c --cipher <algo>". Try 3DES, BLOWFISH and AES - I
have no benchmarks for large files - I can only remember that it took
quite long to test the large file support ;-)

RIJNDAEL should be the fasted. You may want to tweak the IOBUFs (grep
for iobuf_alloc in util/iobuf.c) or the hash buffers (cipher/md.c

I don't know.
