I have to disagree strongly with this statement.  With the right hardware
and software the slip performance is excellent.  Here is my setup.

I have and RT at home.  I took an IBM AT Serial/Parallel card and replaced
the NS16450 with an NS16550AFN.  I ported Van Jacobson's compressed slip and
installed a new asy device driver from Peter Honeyman.  I connect to work
via two WorldBlazer V.32bis modems with V.42 and V.42bis turned on.  If I
ftp a /etc/termcap, ftp reports a transfer rate of 2kbytes/second in either
direction.  The modems are locked in at 38,400 bps with hardware flow control
on.

I usually use local xterms and rlogin to hosts at work.  However, I find it
more convenient to use xmh at work and display at home.  I don't mind waiting
a couple of seconds with wxmap draws the current weather map either.

I can give limited advice on how to achieve the same success.

Hope this helps,  ...Tim
