Reading Results


Understanding and reacting the results from a LoadForge test is more important than the test itself. We have collected some examples here for indicators, errors, and what to look out for in tests.

Summary Data

When you finish a test you will immediately see the "Performance Summary" and "Response Time Summary" figures.

In Performance, we want to look for:

  • Any failures and the number of failures per second as a percentage
  • A below expected number of requests per second

These both indicate an overload on your system. You can look at the Errors tab for more details.

For Response Times there are two primary considerations:

  • The median response time, and if it's fast enough. A typical website should aim for under 300ms
  • The max vs min response times, and if there is a large variance. This can indicate an overloaded system.

You can get a huge amount of information from the "P9x Response times" graph, which shows the difference between the P95 and P99 measurements.


Generally speaking you want smooth consistent lines on graphs. Spikes and choppiness is an indicator of an overloaded system.

You should also aim to see your P95 and P99 lines be close to each other, showing reliable performance.
