build.db-connection-pool Calculator
Calculates the optimal database connection pool size from max connections, concurrent workers, and query latency, based on the Little's Law formula. Too few pool connections cause queue latency; too many overwhelm the database — the optimal pool size is typically (core_count × 2) + spindle_count.
Inputs
Cpu Cores
Reference formula or conversion factor shown for context.
Avg Query Ms
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Target Rps
Reference formula or conversion factor shown for context.
Results
ideal pool size
Number of workers, connections, or instances in the pool. Too small causes queuing; too large wastes resources.
recommended pool
Sample size or count used in the calculation.
utilization
Fraction of capacity actually being used. Above 80–85% is typically considered high utilisation; above 95% leads to queuing and latency spikes.
concurrent queries
Electric charge flow rate (A). Governs wire sizing — too much current causes dangerous heating. Fuses protect circuits from overcurrent.
