Performance testing best practicesΒΆ
When performance testing BIG-IP VE, use an external iPerf Server and iPerf Client with BIG-IP-VE in the middle.

F5 recommends using iPerf 2.0.5 or iPerf 2.0.8.
Download the appropriate iPerf 2.0.8 - RPM package (or iPerf 2.0.5) at: https://iperf.fr/iperf-download.php#fedora.
Use Secure Copy Protocol (SCP) to get the file onto the machine:
sudo yum install iperf-2.0.8-2.fc23.x86_64.rpm -y
On the server, run the following command (inserting your port used):
iperf -s -p [port]
Example:
iperf -s -p 5213
On the client run the following command (inserting your server IP address and port used):
iperf -t 30 -i 10 -c [server_ip] -P 16 -p [port] -w [payload_size]
Example:
iperf -t 30 -i 10 -c 10.75.0.213 -P 16 -p 5213 -w 128MB
This test will run for 30 seconds with 16 sessions, and a 128M payload.
You can run both iPerf3 and iPerf2 on the same system, but the client/server must be compatible.
So,
and .For CLI:
To execute iPerf3, you can use
iperf3 -s -p
To execute iPerf2, you can use
iperf -s -p
Tip
Notice that the command for iPerf2 is just
iperf
and NOT iperf2.
Consult the iPerf web site for changes between iPerf 2.0 and iPerf 3.0/iPerf 3.1.
