Load-test your OPC UA server at scale
Open hundreds of concurrent OPC UA sessions and subscriptions against the WizIIOT OPC UA server and measure live throughput.
What it is
A load and stress-test tool for the WizIIOT OPC UA server. It opens many concurrent client sessions, subscribes each to the full tag tree, and reports how many live updates the server is delivering per second — so you can size deployments, validate stability under load, and prove field-readiness before go-live. Because it speaks the same OPC UA stack as the server, it connects natively with no compatibility fuss.
Key benefits
Realistic load in one command
Spin up N concurrent sessions and thousands of monitored items from a single process to mimic a busy SCADA/HMI fleet — no extra infrastructure.
Measure real throughput
Live updates-per-second reporting shows exactly how the server performs under your load, for capacity planning and tuning.
Native compatibility
Built on the same OPC UA SDK as the server, so it connects and subscribes reliably with no endpoint or session quirks.
Fully tunable
Dial sessions, tag count, publishing/sampling intervals and run duration to reproduce any deployment profile.
Capabilities
- Open a configurable number of concurrent OPC UA sessions
- Auto-discover and subscribe to the full device/tag tree
- Report aggregate DataChange throughput (updates/second) in real time
- Tune publishing and sampling intervals and monitored-item queue depth
- Run for a fixed duration or continuously until stopped
