Make sure the swperf-cl-test utility is successfully built with make. Plug in two or more SwiftRNG devices in USB ports available.

Run the following command:

sudo swperf-cl-test

swperf-cl-test will form a cluster of SwiftRNG devices connected to the system, run general device performance test, and report the random number generation speed in megabits per second.

The output may look similar to this:

sudo swperf-cl-test
