I wonder if we're thinking of the same numbers. I've seen 56k modems run at 14,000 bps on bad lines, but not often. 4,500 bps is pretty slow. > >The change means that the second connection traveled over wires that were > >slightly noisier, or slightly busier, or one of a hundred other > >possibilities.

I've done repeated measurements on connections, gotten consistent results, and discovered a week later that I was getting different results. I would not trust results unless they were consistent over time. I don't know how many tests you did or over how long a period you did them, so you may be right. You didn't mention repeating your test in your first post, and I'll admit I assumed that you did it once. Running ppp in the kernal is supposed to be more efficient. In practice, I doubt it makes a lot of difference. Most of what controls transmission speed is in the modem, not the computer. Some things that affect speed can be negotiated between the computers, and that might make a difference, depending on how you're configured. Or I could be just plain wrong; user PPP might have been tweaked to the point where it works faster. I used pppd until a few months ago, and my recommendation is to go with user PPP, regardless of speed differences. Few people use pppd, so you won't get as much help if you have problems. Roughly 75% of the answers I got when I was asking for pppd help explained how to fix the problem if I were using user PPP. User ppp is much more flexible, and I did a lot of work solving problems on a couple of occasions that could have been solved quickly and easily if I had been using user PPP.
