Ummm ... I think that perhaps I made the impression that I did a thorough
scientific analysis. That's not the case :-)
Here's exactly what happened:
- I remember reading (I _thought_ it was in Steven's TCP/IP) that a lower
MTU would improve interactive response time. So I set it down, and
things _seemed_ better, but I didn't have any hard data.
- At a later date, I thought about it, decided that it really didn't make
sense, and I set the MTU back up in my PPP startup script, but I didn't
- The next time I rebooted, I said, "why are my sessions so terrible in
response time?". I poked around, realized that I set the MTU higher
and forgot about it. I set it back down, and things started behaving
the way I remembered that they did.
That's it. Note that a couple of months passed between #1 and #2. However,
the fact that I noticed a difference when I had forgotten that I changed
it convinced me.
