Fixing Bottlenecks

The Fix-and-Verify Loop

Fixing a bottleneck without verifying the fix is just guessing. Make sure to always follow this workflow:

Identify bottleneck
       ↓
Implement fix
       ↓
Re-run test at the same load level and duration
       ↓
Compare results against baseline
       ↓
Did the target metric improve?
 Yes → look for the next bottleneck
 No  → the fix did not address the actual root cause, investigate further
