Using the latest Chrome browser, poor linear scalability is experienced after 30 browsers regardless of the size of the test node.
### Example System Requirement Calculation
If a test specification requires UX tests to run 1000 virtual users, and each test node has an 8 Core CPU with 12 GB RAM, then 20 test nodes are required.
Calculated as:
- Test Nodes Required = Total Virtual Users / Virtual Users per Test Node
- (from the above example) 20 Test Nodes = 1000 Virtual Users / 50 Virtual Users per Test Node
