I don't think you're really seeing a problem that can be fixed. I
see this with Linux, too, for what it it's worth. The problem is
that the 33.6Kbps is just a nasty slow tunnel, through which your
sports car is trying to speed. Compared to a P200, that modem is
almost standing still.
Some programs seem to be worse bwith hogs than others. FTP seems to
be the worst offender; start an ftp session, and nothing else ever
seems (i.e. it takes two minutes ;) to get a packet through.
I hope a kernel dude will step forward. It just seems like there's
no sharing going on with the ppp channel.
