The following list describes the parameters for the netperf command:
-H
192.168.0.1
-c
-C
--
-m
The notable performance values in the example above are as follows:
Throughput is 6.60 gigabits per second.
Client CPU utilization is 23.79 percent of the client CPU.
Server CPU utilization is 21.37 percent of the server CPU.
Run the Netperf Latency test, which forces SDP to be used instead of TCP.
Step 6
After the test runs once, stop the server so that it does not repeat the test.
The following example shows how to run the Netperf Latency test with SDP:
host2$ LD_PRELOAD=libsdp.so LIBSDP_CONFIG_FILE=$HOME/libsdp.conf netperf -H 192.168.0.1 -c
-C -t TCP_RR -- -r 1,1
TCP REQUEST/RESPONSE TEST from 0.0.0.0 (0.0.0.0) port 0 AF_INET to 192.168.0.1
(192.168.0.1) port 0 AF_INET
