Tesseract is currently compiled to target SSE4, which Emscripten can map to WASM SIMD instructions. It has code which supports improved vector instructions beyond SSE4 (AVX, FMA). If it is possible for Emscripten to target these when configured to target WASM relaxed-simd (see WebAssembly/relaxed-simd#52), this could result in additional speed-up during text line recognition.

WASM Relaxed SIMD is currently supported in Firefox 103 and is being worked in Chrome.
