Going to a 10/100 NuBus card probably won't help too much if you're on a =
10 MBit router/network,
but it might be worth a try if you have a spare one lying around...
Some things I'd check:
1) try a new cable from the quadra to the router
2) use the iostat program and "top" to help determine if the quadra is =
IO-bound or CPU-bound...
it might be IO-bound if your disks are slow, you've got a lot of other =
accesses going on on=20
the same disk, or if you've got too much stuff going through the bus. =
CPU-bound would
just be a netatalk issue...
3) Especially if you're CPU-bound, but regardless, I'd renice -20 =
<netatalk pid> to and see if the higher priority helps any...
4) use ifconfig -a to check that the mtu for your ethernet card is 1500 =
or greater
Other debugging techniques:
a) run tcpdump on the quadra and see if there happens to be lots =
of other=20
network traffic going on and hence maxing out the =
network interface
b) plug into a different port on the router -- voodoo, I know, =
but...
My NetBSD box is down, otherwise I'd hook you up with some benchmarks...
