Here’s How Microsoft Edge Uses Disk Caching For Better Performance


Through a blog post, Microsoft announced that it will use disk caching to try to “deliver the best performing browser possible on Windows and other platforms,” starting with Microsoft Edge 102.

Disk caching is a technique used to speed up the process of storing and accessing data from the host hard drive while reducing the disk footprint. At some point, you may have had a less than pleasant browsing experience, which may indicate that your browser is using too many resources, which in turn is slowing it down.

Microsoft further said that they have carefully considered cache size management, especially when dealing with devices that may not have enough disk space. Disk caching can cause the user to run out of disk space, but browsers use this technique using the available space.


Instead, Microsoft has turned to compressing files, which doesn’t require a lot of disk space. Based on the fact that “these caches are often highly compressible, compression increases the likelihood that the requested resource can be retrieved from disk.”

According to the blog post, “Starting with Microsoft Edge 102 on Windows, Microsoft Edge automatically compresses disk caches on devices that meet eligibility checks, to ensure that compression will be beneficial without degrading performance. This ensures that compressing these caches greatly improves performance and overall user experience.”
