It is not immediately obvious why a local filesystem would be slower than network

  Well. I mean, get a slow enough hard drive and a nice enough network and we can get there, haha.

    If you live in a rich country and are on fiber internet rather than a cable modem (or if your cable modem is new enough), you likely have better latency to your nearest CDN than you do to the average byte on an HDD in your computer. An SSD will still win, though. The browser cache is kind of like a database and also tends to hold a lot of cold files, so it may take multiple seeks to retrieve one of them. Apparently it has throughput problems too, thanks to some bottlenecks that are created by the abstractions involved.

  On ‘recent’ files your operating system will most typically not even touch the disk because they will aggressively cache those files in memory
