yes, setting the port delay to zero may speed things up for you, or
it might cause the backup not to work. YMMV. setting the -b option
in GNUtar to 64 ( = 32768 / 512) should get you blocking at the same
throughput as the port.

IMHO the best way to do this is to to an 'ls -lR' of the tree you're
backing up, and specify that file first in the tar line so it's the
first thing in the archive. voila, catalog. and even portable ;-)
