In a computer-based test (CBT) environment, every component—from server to network switch to terminal machine—affects the candidate’s experience. When planning a high-load online exam, it’s critical to simulate real exam conditions ahead of time. That’s why Addmen offers a Lab Testing Utility: a tool that mimics online exam load across multiple machines, helping you verify that your lab infrastructure can deliver reliably under stress.
Detect Weak Links in Infrastructure
Even if you invest in high-end server hardware, your network switch, LAN cables, or terminal PCs may be the bottleneck. The utility helps flag those.
Quantify Your Lab’s Capacity
Simulate many users to find out exactly how many simultaneous terminals your setup can support without performance degradation.
Measure Question Delivery Speed
You’ll get metrics on how quickly exam content is delivered to each terminal under load.
Identify Slow Terminals
Some PCs in your lab might lag behind others—this tool helps find which ones need attention.
Track Degradation Over Time
Lab performance may degrade over time due to OS updates, background load, or hardware aging. Re-run tests periodically to check for drift in performance.
Explain Performance Variation
When questioned “Why was the exam slow today?” you’ll have empirical data to pinpoint whether it's environment changes (network, OS, hardware) affecting performance.
Load Simulation from Multiple Terminals
It generates simulated exam traffic from many terminal machines to the server, just like a real exam scenario.
Collect Performance Data
For each simulated session, metrics are recorded (e.g. response times, delivery latency, resource usage).
Analysis & Reporting
The results help you analyze whether your server, network, or lab machines are limiting factors.
Inference & Recommendations
Based on the test results, you can predict how many concurrent users your lab can reliably support, and identify which component (server, switch, terminal) needs upgrading.
Don’t rely on “it worked once” — retest regularly (after hardware changes, OS updates)
Use the same load profile (number of users, question complexity, media) as your real exam
Monitor all layers: server CPU & memory, network latency & switch throughput, terminal response times
Establish safety margins (e.g. don’t push your lab to 100% capacity during exams)
Document baseline performance so you can compare future test runs and detect drift
