Steganography just means a slight reduction in payload capacity. instead of
passing 1200 bytes of payload at a time, it would be maybe 1140. So worst
case 5%-10% reduction in bandwidth.

If you are going to do any form of traffic analysis defeat with onion
routing or the like, you are obviously going to increase latency according
to your path lengths. But no reason it shouldn't be acceptably fast if you
have a modern network and modern hardware.
