Structs

Measurement	A simultaneous measurement of at least two of the parameters of Little’s Law: concurrency, throughput, and latency. The third parameter is inferred from the other two.
Model	A Universal Scalability Law model.

Constants

MIN_MEASUREMENTS

The minimum number of measurements required to build a model.
