dev.thread-pool-sizing Calculator
Calculates the optimal thread pool size for CPU-bound vs I/O-bound workloads from core count and blocking time ratio. Thread pool sizing formula for I/O-bound: threads = cores × (1 + blocking_time/compute_time) — too many threads causes context-switching overhead; too few wastes CPU.
Inputs
Cpu Cores
Reference formula or conversion factor shown for context.
Io Wait Pct
Reference formula or conversion factor shown for context.
Target Utilization Pct
Reference formula or conversion factor shown for context.
Results
optimal thread pool size
Number of workers, connections, or instances in the pool. Too small causes queuing; too large wastes resources.
CPU cores
Reference formula or conversion factor shown for context.
I/O wait ratio
The proportional relationship between two quantities.
Little Law: threads = cores × (1 + wait/compute)
