Bitsum’s System Responsiveness Metric

Nearly 2 decades ago, Bitsum developed a clever algorithm to accurately represent the system responsiveness of a Windows PC. Our algorithm is one of those ‘so simple it’s beautiful’ type inventions. We never bothered with a patent on it, having some ideological opposition to software patents at the time of the algorithm’s conception. This metric has since been used in several Bitsum products.

Our system responsiveness metric is amazingly accurate. It’s been in real-world use over a decade, so is very mature and well tested. If you’d like to license this technology, email us at

At present, this metric is featured in Process Lasso, CPUBalance, and the CPUEater ProBalance demo.
