X-Newsreader: NN version 6.5.0 #0 (NOV)

Netbsd 0.9 on a 486/20 AMD DLC

Hayes 28.8 modems running cslip, DTE at 57600
Local hayes with ESP board.
At 28800, we should be able to achieve 3600 bytes/s


Xfers seem to jump to ~5800 bytes/sec when starting news (text)
A higher DTE _might_ help, but probally not as we're not hitting 7000+.

ftp text: 390491 bytes sent in 90.97 seconds (4.19 Kbytes/s)
4.19 * 1024 = ~4290 bytes/s

ftp binary: 103705 bytes sent in 40.32 seconds (2.51 Kbytes/s)
2.51 * 1025 = ~2570 bytes/s

The xfers seem to run really fast (2000 - 3000 bytes/s) and then drop 
to nothing for a second.  This may be a quench from somewhere... something
to debug.

Does anyone have reading about what CSLIP vs SLIP actually saves you?  I
may change over to SLIP to do some more testing.  These numbers were all
obtained by hacking netstat to produce the struct ifnet if_ibytes and
if_obytes members.
