Also, since I wrote that article, we shipped wasm to Squoosh that makes use of threads. We aren't there with SIMD yet (for AVIF, we have it for some other codecs), but tooling is getting better.
That's awesome. Do you have a rough value on what the best case effort=10 encoding is right now (in CLI, decent computer), compared to the 10m number given above? Will it be 10x faster? 100x faster?
