Performance testing knowledge record

Either don't do it, if you want to do it, do it for the best, rigorous.

1, performance test index, comprehensive measurement of system performance. Used to describe the performance of the system and the results of the performance test

TPS, concurrent users, response time, business processing capacity (traffic per second), hardware metrics (CPU, memory, disk IO)

2. Performance-related configurations. Learn in advance the configurations that will affect system performance.

Running memory size, memory size, CPU

3, performance test cases, consider user scenarios, predict user behavior. Just take what you need. Avoid omissions and encumbrances.

4, business flow, data flow. The way it works. Deployment diagram. The core business point of performance testing, the main user point, the point that is prone to performance problems. The purpose of performance testing. Error-prone points.
