Turns out you can make btrfs dedup about 10x faster by just... reading the data before you deduplicate it. FIDEDUPERANGE byte-compares every range first, and if it has fallen out of the page cache that is a cold read. Prime it and it isn't. github.com/martinus/oans

TIL I could reduced my boot time by about 15 seconds by setting "Memory Context Restore" in the BIOS from Auto to Enabled. On an AMD system, TUF Gaming B650-Plus Mainboard. The setting is somewhere under Ai Tweaker > DRAM Timing Control.
