There was a Mastodon post some time back (~1y?) where someone realized that the fastest RISC-V hardware they could get was still slower than running it on QEMU.

That's not how it usually works :\

RISC-V is certainly spreading across niches, but performant computing is not one of them.

Edit: lol the author mentions the same! Perhaps they were the source of the original Mastodon post I'm thinking of.
