Nothing jumps out at me, but a few things you might try:
1) Simplify: use pppd instead of diald until you sort this out. And work
on the server, not the client box.
2) Debug: get your modem to report its connect speed. You'll have to look
up how in your manual. Put the necessary AT command into the chat script,
and turn on debugging so you can see the connect speed in the logs.
Also, try just a plain serial connection with minicom, and see what kind
of speed you get using Zmodem transfers. (Or kermit transfers, but kermit
is notoriously hard to configure for maximum speed.)
3) Use ncftp or lynx to display the number of bytes transferred in real
time, and then watch the hard disk light. If the disk flashes every time
there's a slowdown you might want to try the hdparm utility to unmask IDE
hard drive interrupts. Read the manual carefully, though, and test it on
expendable data first.
4) You might also want to try irqtune.
5) I noticed you use 127.0.0.x addresses for the dummy addresses in your
conf file. You should try using 192.168.x.x addresses for those (although
be sure not to pick addresses that correspond to actual computers on your
network ... maybe reserve a whole dummy subnet 192.168.254.x or something
like that).
