Cloudflare says it prototyped Cache Transcoding, a system that compresses eligible cached assets with Zstandard before storing them on disk and moving them between data centers. The company reports this can cut eligible assets to about one-third of their original size on average, trading a small CPU increase for lower storage use and less cross-data-center bandwidth.
