Performance

Optimization

Parser

• Light&Permissive indexing parse
  • Also sets us up nicely for telemetry collection, bc that will be on access, not up-front.

SIMD

Looks promising, but until we see performance it's not worth the required conditional deploy (bundle.js vs bundle-simd.js).

• when enabled, wasm-objdump shows ~3k v128 instructions in the conway.wasm, but not showing any performance diff in node v16 or v18 on Schep despite landing in v16 https://webassembly.org/roadmap/.
• Discussion: discord#eng on simd
