dev.build-time-optimization Calculator
Calculates build time improvement potential from parallelisation, incremental builds, and caching of build artefacts. Build time compounds across a team — a 10-minute build for 20 engineers wasting 5 minutes each equals 100 engineer-minutes per build run.
Inputs
Build Time Sec
Rate of charge flow (A). I = V/R. Above ~100 mA through the body can be lethal. Fuses protect against overcurrent.
Parallel Jobs
Reference formula or conversion factor shown for context.
Cache Hit Rate
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Team Size
Reference formula or conversion factor shown for context.
Results
optimized build time (s)
The computed duration or time value.
current build time (s)
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
speedup
Factor by which the improved approach outperforms the baseline. 2x speedup = half the original time.
dev-hours saved/month
The total amount saved compared to the baseline scenario — cost savings, time savings, or resource savings.
savings at $100/hr
Total money or resources saved compared to the baseline or alternative scenario.
cache impact
CAC (customer acquisition cost) -- total sales and marketing spend divided by new customers acquired. Healthy LTV:CAC ratio is 3:1 or higher.
