Rick,

Thanks for getting back to me. I have been running several tests on two =
Sparc machines both running on 100Mb link via switch (100Mb CISCO). From =
both ends I ran netserver then the netperf commands as shown below. Why =
am I getting a different throughput link on both cases ? I deally I =
though they should be the same !! I have been trying to check whether =
the problem could be one of full- or half- duplex link setting, but with =
no much success.

Anyone with ideas, I'll appreciate !! The outputs are show below.

Martin.
