I've got a laptop running NetBSD/i386 -current (as of 20010820), and I'm
getting some seriously lagged network performance on it.
It's hardware configuration is:
K6/266mhz CPU, 32MB ram, 3.8GB disk, with a Linksys PCMPC100 Fast Ethernet
PCMCIA NIC.
According to my switch, the card is synced at 100BaseTX Full-Duplex, and I
will see burst speeds sometimes at a few megabytes/sec like I *should* with
100mbit/fdx, but most of the time (say if I'm transferring a large file), I
get speeds averaging around 14 KB/s.
Any ideas as to what's wrong?
Any help would be seriously appreciated, as this is quite a PITA when trying
to update the system via files on eros, the main server on my LAN (networked
via a thunderlan card, and I get great speed from eros to the other machines
with 100tx adapters on my LAN, so I am sure the problem lies somewhere in
the laptop's configuration.)
dmesg output, and kernel config file follow.
