I think that term only has generic compression.  This is probably
not optimal for X packets where a lot of the overhead is in the
relatively big (nearly) duplicated headers.

I tried term for running X applications over a V.32 modem link.  The
performance of an NCD X-terminal (with XRemote, which is approx
equiv to LBX) was significantly better over the same link.  If I
could figure out how to "use" LBX, I'd give it a try.

BTW, the fastest channel multiplexer I've found is layers (a unix
client for MacLayers).  It provides very low overhead multiple
terminal sessions over a single link and file transfer (via zmodem),
but no additional features like IP redirection or remote X
connections.  Editing over a 9600 bps link feels like a straight
9600 bps link, unlike term, which feels as bad as SLIP.  File
transfer nearly maxes out the available bandwidth.  Of course,
response does slow down a bit during file transfers.
