The feature adds a performance.measureUserAgentSpecificMemory() function that estimates the memory usage of the web page. The website needs to be cross-origin isolated to use the API.
Motivation
Web developers need an API for measuring memory usage of their applications in production. The use cases include a) analysis of correlation between memory usage and user metrics, b) detection of memory regressions, c) evaluation of feature launches in A/B tests, d) memory optimization.
