Identifying Bottlenecks

Summary

Diagnosing where a system actually slows down under load — database queries, external API calls, or application code — requires correlating performance test results with system-level monitoring.

• 1Given a hypothetical performance test result, list 3 possible bottleneck sources to investigate.
• 2Learn why isolating a bottleneck often requires monitoring at multiple system layers simultaneously.
• 3Understand this investigation often requires collaboration with engineers and DevOps.
