The following list describes 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.
Step 4 Run the Netperf client.
The default test is the Bandwidth test.
The following example shows how to run the Netperf client, which starts the Bandwidth test by default:
host2$ netperf -H 192.168.0.1 -c -C -- -m 65536
