About the *only* X11 client that works well over *dial-up* (or other
low-speed and/or high-latency connections) is the old XAW-flavored
xterm (I use it all of the time).  For pretty much all other X11
clients, you really need a local LAN connection (eg 10BaseT or better). 
This is partitularly true for any sort of non-trivial GUI (like a
graphical web browser for example).

X11 is not really designed for truely 'remote' usage.  X11's idea of
'remote' is like 'down the hall' or 'across the room' or 'down in the
basement server room of the building your office workstation is in'. 

Unless of course you have a 100mbit fiberoptic link to the Internet
backbone. :-)
