open62541 Performance Test Scripts

Read Speed

This test reads a variable as often as possible while running and measures the average time it takes between reading two values.

Usage:

./read-speed-server
./read-speed-client opc.tcp://server-ip:4840

Output when running both scripts on the same host:

------ Starting reading loop. ------
