> So, is the an efficient way to leverage the speed improvement for other than swap -- like binary caching of executables of some form? Sure. Like the site I mentioned in other comment, more or less "out tracks are faster". But this applies just to HDD drives. It's mostly useless for modern infrastructure, like SAN (even HDD based), all kinds of SSD and so on. A curiosity - last time I saw a cool optimization of HDD usage was on "old gen" consoles, like ps4 and xbox one. Most games duplicated assets multiple times. Games took much more GB then needed, but the drive did not had to jump between many HDD tracks so much and it mattered for instance in big open world games.
