Evaluate Linear Scalability

Evaluate Linear Scalability
Linear scalability compares how the application responds as load increases. A scalable system should increase throughput predictably while keeping response times and errors within acceptable limits.
What to compare
Virtual users or request volume at each load level.
Throughput and transaction completion rate.
Response time trends, including percentile behavior.
Error rate and application or infrastructure saturation signals.
Recommended workflow
Run controlled tests at increasing load levels.
Keep test data, environment, and scenario mix consistent between runs.
Compare steady-state periods instead of ramp-up or unstable intervals.
Identify the load level where throughput stops increasing or errors rise.
