I dunno, it’s hard to take all this magical ram software cache stuff seriously after the failure of Intel Optane

and the failure of Vista’s ReadyBoost

not to mention the failure of weird hybrid HDDs that had partial SSDs for “cache” on them… remember those?

What do all these techniques have in common? Trying to make a slow interface faster by globbing a little bit of something faster in between. And they all failed. In general this path – the path of using “a special cache layer” has, at best, a checkered history in the computer industry.
It’s the job of the operating system for the last forty years to cache frequently needed info in unused system memory as a matter of normal operation. This is an extremely mature area of computer science, to put it mildly.
So why the magical software? I mean heck we already know ramdisks are completely not worth it for chia… and that’s going all the way.
