Google is experimenting with increased storage for the browser cache to reduce the performance hit caused by the recently added partitioned cache feature. Google added a new feature to Chrome 85 that partitions the browser’s disk cache so that each site utilizes its own cache that cannot be read by other sites. Google plans on testing cache storage that is 2x, 2.5x, and 3x the normal cache size. Google is hoping that increasing the storage will reduce the number of times the browser has to remove older cached items as storage runs out.
