Neither is "best".  I would think SLIP would be faster, simply because
it's less complex.  PPP is more robust, since it can route lots of
protocols over it, not just IP like SLIP does.  But, how many times
are you going to need to route AppleTalk or DEC LAT over your serial
connection?

I run PPP just because I like the flexibility it has with
configuration options, and it just seems a little bit more robust
(i.e. recovers quicker from corrupt packets, etc.).  On the other
hand, my co-worker runs SLIP on his connection and seems real happy
with that.  My experience is that SLIP "feels" slightly more
responsive and quicker, simply because it doesn't have to do as much.

Only your use will determine what you like best.  Why not just try
them both?  That's what I did.  You have both built in to NetBSD, so
just give them both a shot and use the one you like best.

If I'm not mistaken, NetBSD-1.0 SLIP *is* CSLIP by default.  Correct
me if I'm wrong.

Ya know, I would have thought ifconfig would be the command to change
an MTU, but it's not in there.  Dunno what you'd use, if it's even
possible.  Try sifting through the source -- it may have to be a
compiled-in value.
