Hi,

I'm getting < 15 KB/sec on a local 10 Mb/s Ethernet between the NetBSD
machine (400 MHz K6-2/128M DRAM) and a BSDI 4.0 box with a PP150.  Between
the BSDI box and a 486/66 with 1.4.1 I'm seeing about 650 KB/sec.

The 400 MHz K6-2 box has an on-motherboard Davicom 10/100 ethernet that I'm
not using (but can't disable from the bios).  I'm using a Realtek 8039 PCI
card for ethernet connectivity.

The load average on the machine during ftp transfer is very low.

Oh, and I've noticed that when I telnet to the 400 MHz K6-2 box with 1.4P,
often after typing maybe only half-dozen characters, the next characters
are not echoed immediately - very disconcerting when you expect an 
immediate echo.

And pointers would be appreciated.  My dmesg is below.

-Mike
