It'd be interesting to compare it to a SHA-256 algorithm that uses Wasm simd: https://github.com/ChrisWhealy/wasm_sha256

Noted, will add that.
Last time I tried https://github.com/Daninet/hash-wasm
edit: I focus on browsers, that's wasm but not for browser envs.

seems it is chrome wasm that is slow.
asmjs is about the same speed in chrome and firefox (with asm optimizations still enabled) but wasm is slow as hell in chrome, asm still better.
side note: someone mentioned native crypto.subtle, but that doesn't have incremental hashing so can't use it for large files. however I do use it in practice for smaller files.
