Brian,

here aare soem results (all very reproducible)


I just posted some of my boot problems with .90f and .90k

I also put some netgear Lite-On Nics in our cluster
to check some things:

NETPERF:  21140 NIC (.90f driver)  ---> LITE-ON (.90k driver)

Using the other NICs in my cluster I get between 94-95 Mbits/sec

I may try patching .90f as suggested and see if it works better with
the Lite-On card.  

My test script:

./netperf -t UDP_STREAM -p 12865 -n 2 -l 60 -H coyote$1 -- -s 65535 -m
1472
./netperf -t TCP_STREAM -p 12865 -n 2 -l 60 -H coyote$1
