Google is experimenting with increased storage for the browser cache to reduce the performance hit caused by the recently added partitioned cache feature.

To prevent these side-channel attacks, 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.

To improve this feature's performance, Google is experimenting with increased disk cache sizes to prevent resources from being evicted from the cache to quickly.

"Add code to enable experimentation of different http cache sizes. Now that cache will be partitioned, it makes sense to see if increasing the cache size helps offset some performance impact by lowering the eviction rate," Sharma explained in a Chrome Gerrit post.

As part of this test, the browser's performance will be measured at different disk cache sizes to see if increasing them to larger values positively impacts performance.
