Diminishing Returns of Optimization

Each successive optimization typically yields smaller improvements than the previous one; at some point, further optimization cost exceeds its benefit

Tension Addressed

Simplicity vs. Performance

Recognizable As

Law of diminishing returns, 80/20 rule applied to performance, optimization ROI analysis

Canonical Sources

Amdahl, "Validity of Single Processor Approach" (1967); Brooks, "The Mythical Man-Month" (1975)

Transfers To

Economics, project estimation, resource allocation, optimization theory

This concept connects Amdahl's Law (mathematical limit) with Knuth's wisdom (practical limit). Even before hitting theoretical limits, the cost-benefit ratio of optimization shifts as easy wins are exhausted.
