Conversation transcript
An illustrative conversation about a slow application, where to look for a bottleneck, and what to measure next.
Understand · Testing assumptions · Seeking evidence
Human 1
We added a second server, but our application is still slow. Why?
AI 2
It depends on where requests spend their time. If both servers wait on the same database, adding application capacity may leave that bottleneck unchanged.
Human 3
What should we measure before adding a third?
AI 4
Compare request latency, database wait time, and application utilization under the same workload. That can help you locate the delay before choosing a change.
Human 5
Could our load test itself be the bottleneck?
