⚠️There's a newer version (3.0.4) of this package.Take me there.

usl (version 1.3.0)

Analyze system scalability with the Universal Scalability Law

Description

The Universal Scalability Law is a model to predict hardware and software scalability. It uses system capacity as a function of load to forecast the scalability for the system.
