How response speed changed over time
Typical response time
Slower moments (95th percentile)
The solid line is what most requests experienced; the dashed line shows the slower end — what unlucky requests felt like. The closer the two lines are, the more consistent the experience.
Users & traffic over time
Concurrent users
Requests per second
As more simulated users joined, this shows how many requests per second the system handled. If speed stayed steady on the other chart despite more users here, that's a good sign of stability.
Errors over time
Failures per second
Spikes here show moments when requests were failing. Worth checking whether they cluster at a particular point — like right when more users joined.
