Just the same as you. netperf -H ... -- -s 1M -S 1M to a linux receiver (dual dual core woodcrest, barely even noticed a 2.2Gb/s load), 1500B MTU. The linux host was running netperf 2.4.3 (kernel 2.6.22), and the sparc was running netperf 2.4.2 (solaris S10U4): % netperf242 -H10.0.130.183 -C -c -l60 -- -s1M -S1M TCP STREAM TEST from ::ffff:0.0.0.0 (0.0.0.0) port 0 AF_INET to ::ffff:10.0.130.183 (10.0.130.183) port 0 AF_INET Recv Send Send Utilization Service Demand Socket Socket Message Elapsed Send Recv Send Recv Size Size Size Time Throughput local remote local remote bytes bytes bytes secs. 10^6bits/s % M % S us/KB us/KB 2097152 1048576 1048576 60.00 2239.60 4.31 4.56 5.049 0.667 Sendfile helps a little: % netperf242 -H10.0.130.183 -C -c -l60 -tTCP_SENDFILE -F /var/tmp/zot -P 0 -- -s1M -S1M 2097152 1048576 1048576 60.00 2705.02 6.45 6.03 6.252 0.730 (it takes a few streams to get up to line rate on a cool threads machine :) Anyway, if you've got an LSO implementation, I'd really like to see LSO results compared to MDT results on the same hardware.
