I'm sending this to the list because I make a comment below that should
really belong in a seperate post. ;)

My PPP performance reeks during FTP or any kind of bandwidth-consuming task.
It's been like this since version 1.x. Maybe my math is screwed up here, but
if I have a telnet session and an ftp session running, and the FTP session
sucks all the bandwidth it can find, and I have an MTU of, say, 1006, and
I'm getting a transfer rate of at least 1.1k/sec. net, why would it take any
more than one second to transfer data destined for another socket? Dropping
the MTU to 552 or 296 doesn't seem to help much. Other folks have said this
isn't a problem in Windoze 95, but I don't run it so I can't check myself.

Did you forget the patch? ;)
