What triggers this finding
A Lambda function with at least 512 MB of memory, more than 1,000 invocations in the lookback window, and average duration under 200 ms — indicating memory is likely over-allocated.
Typical fix
Reduce memory allocation toward 128–256 MB and re-test. Lambda bills proportionally to memory, so rightsizing can cut cost without hurting performance.
Example savings
Varies by invocation volume — flagged when estimated monthly cost is at least $1; high-traffic functions can save $50+/month.
