Because I heard some alarming things about uucp-throughput, I decided to
build a test situation. The result of the first test was quite surprising:

uucico waubel - (1995-11-29 22:32:15.13 346) Login successful
uucico waubel - (1995-11-29 22:32:15.88 346) Handshake successful (protocol 'i' sending packet/window 1024/16 receiving 1024/16)

uucico waubel - (1995-11-29 22:40:50.74 346) Call complete (516 seconds 742632 bytes 1439 bps)

Both files were compressed using 'gzip -9', to rule out the compression
build in to my modem. It's a 9K6 modem, that was communicating with my atari
at 19k2. Although the number of errors was quite high, throughput was not
bad. I used a ZLRB_RING_SIZE of 4096 (standard 1.1 BOOT kernel) and
hw-handshake (hardflow true).

Comments?
