Here's some data. Maybe there's some issue with the Linux driver for
my Xircom cardbus Tulip card. I'll explore further.

The thing that weirds me out the most is that my throughput to, say, an
ftp server on the 'Net where I have to go *through* my NetBSD gateway
far exceeds my throughput *to* my NetBSD gateway. I'm not sure that I
understand this.

Machines:

NetBSD gateway running 2.99.10/i386
Debian desktop running 2.6.8/i386
Debian laptop running 2.6.8/i386

NetBSD is client, Debian laptop is server:

Packet size  1 KByte:   19363 Byte/s
Packet size  2 KByte:   10985 Byte/s
Packet size  4 KByte:   10426 Byte/s
Packet size  8 KByte:   11459 Byte/s
Packet size 16 KByte:   11459 Byte/s
Packet size 32 KByte:   13095 Byte/s

Debian laptop is client, NetBSD is server:

Packet size  1 k bytes:   587 k bytes/sec
Packet size  2 k bytes:   1161 k bytes/sec
Packet size  4 k bytes:   1024 k bytes/sec
Packet size  8 k bytes:   1166 k bytes/sec
Packet size 16 k bytes:   568 k bytes/sec
Packet size 32 k bytes:   493 k bytes/sec

I'm not sure what causes the disparity between these two runs. This wasn't
a fluke result.

'I' before 'E', except after 'C', unless the word is sufficiently weird.
