Ah, so I would like to see that tech built into Steemd itself so it always stays compressed - even when it's running. I know this will add CPU overhead, but since AMD's EPYC and Intel's Skylake-X response, we are headed into a world with more CPU cores than we know what to do with. I know some have experimented on zram on Linux, and it works fine. Anecdote - back when Steemd ran on Windows, the in-built RAM compression in Windows 10 kicked in. Back then, it was all on RAM (no shared_memory) and a full node typically used 15 GB. In Windows 10, that was down to only 3 GB, the CPU overhead was minimal and it ran flawlessly. Of course, very different times now, but I'd be looking forward to seeing compression tech built into Steemd.
