Google is testing larger cache sizes in Chrome to reduce cache partioning impact
Google introduced support for partitioning the cache of the company's Chrome web browser when it launched Chrome 86 earlier this year. The feature changes how web browsers cache content. Previously, web browsers like Chrome used a single cache to store content. One benefit of this approach is that all sites may make use of a cached resource, say a web font or image to speed up the loading of a page or application.
Use of a single cache opened up the door for attacks as sites could check for the existence of cached entries for use in tracking and other attacks.
