V42.bis is supposed to be smart about compression and not compress
things that already look compressed. MNP-5 compression, on the other
hand will actually make compressed images larger.
I have gotten good performance leaving V.42bis compression ON and
turning OFF term's software compression. As suggested above, I set
port speed to 38400 (both ends), escape nothing, and connect at V.32BIS.
Remote non-intensive X clients run pretty decently under this
configuration. And I get close to 1500cps on tupload (with another
trsh running).
One thing I am wondering about: I guess there is a prioritizing scheme
for term clients, right? If I have, say, two trsh's running and fire
up a tupload, it runs slower than if I only ran the tupload. If I close
down one or both of the trsh clients I would expect the tupload
performance to improve, but it doesn't. It's as if the priority was
not increased. I noticied this by running tmon. Anyone else see this?
