optimoinut
Optimoinut is a term used in some online technical communities to describe a philosophy or practice oriented toward optimization at a fine-grained, micro-architectural level. Proponents frame optimoinut as a disciplined approach to improving software performance by systematically identifying and refining the smallest hotspots, rather than pursuing broad architectural rewrites. The term may refer to techniques such as careful profiling, cache-friendly data structures, inlining, loop unrolling, and compiler hints, applied selectively to critical code paths while keeping overall maintainability in view.
Coined apparently in the early 2020s in blogs and forum discussions, optimoinut combines "optimize" with a suffix
Practitioners typically rely on measurement-driven development: establishing performance budgets, using profiling tools, running benchmarks, and verifying
Critics describe optimoinut as a potential distraction from higher-value work and a source of technical debt
