When Sun switched from 68k to sparc, the decided that ring buffers
were a good thing as compared to clists. Thus, a Sun 3/60 had better
serial throughput than a sparc 1+.
To this day, the serial driver in Solaris sucks.
That explains it. I was about to reply and say I was running a uucp
news feed over a 28K modem on a 3/80. But then again I did have a lot
of trouble with silo overflows. And the poor thing is struggling
mightily at the recieving end of a T1 newfeed from Alternet.
