dev.perf-thread-pool Calculator
Calculates optimal thread pool size for a given workload from CPU cores, I/O wait ratio, and context switching overhead in a application performance engineering context. Optimal thread pool size for I/O-bound work ≈ cores × (1 + IO_wait_time / CPU_time) — for CPU-bound work, the pool should equal the number of cores.
Inputs
Rps
Amount per unit of time or per unit quantity. Check the denominator before interpreting.
Latency
Duration of the process. Make sure units match the rate inputs (seconds, minutes, or hours).
Headroom
Reference formula or conversion factor shown for context.
Results
min threads (Little
Sample size or count used in the calculation.
with headroom
Buffer between current performance and a limit or target. Positive headroom is safety margin; zero or negative headroom means the limit has been hit.
queue at peak
The value at the specified point or condition.
daily requests
Reference formula or conversion factor shown for context.
daily p99 budget
99th percentile latency -- only 1% of requests are slower. Captures tail latency that affects the worst-case user experience.
