Contract compatibility
API performance
PERFORMANCE
Speed up a critical request using measurements.
Find the bottleneck, change processing or data access, then compare response time before and after.
What we verify
Response time before and after
These examples show the approach. The plan depends on your system and constraints.
How work is organized
