Microsoft says Microsoft Edge users will notice improved performance and a smaller disk footprint because the web browser now automatically compresses disk caches.

"Beginning with Microsoft Edge 102 on Windows, Microsoft Edge automatically compresses disk caches on devices that meet eligibility checks, to ensure the compression will be beneficial without degrading performance," the Microsoft Edge Team said Wednesday.

"This ensures compression of these caches largely improves performance and overall user experience."

As the company explained, the larger the disk cache a web browser uses, the likelier it is that cached web resources can be accessed quicker, making it faster to load web pages.

However, increasing the disk cache will often lead to systems with low disk space running out of space, which browser vendors also have to consider.

"One way we can maximize cache usage while minimizing disk usage is by leveraging compression to save disk space for the cached content," Microsoft added.

"Since the contents in these cache(s) are often highly compressible, compression results in increasing the likelihood that the requested resource can be fetched from the disk."
