How to cache wasm module in nodejs, or it's already cached on startup ?

according to this https://github.com/rustwasm/wasm-bindgen/issues/2473

Summary

I created comparison between manual javascript haversine function, and wasm based.
the result if i compared including the module initialization, wasm based getting much slower than javascript itself.

Additional Details

console.time("manual")
const haversinee = require("../func/haversine")
const src = {
    lat: -7.0,
    lng: 7.0
}

const dst = {
    lat: -8.0,
    lng: 8.0
}
console.log("manual js : "+ haversinee(src, dst, false))
console.timeEnd("manual")

console.time("wasm")
const {Point, haversine} = require("haversinecalc") // this is the problem

const src_p = new Point(-7.0,7.0)
const dst_p = new Point(-8.0,8.0)

console.log("using wasm : "+ haversine(src_p, dst_p))
console.timeEnd("wasm")

Result with module initialization included

manual js : 156581.10278754708
manual: 12.337ms
using wasm : 156581.10278754708
wasm: 18.109ms

Result without module initialization

manual js : 156581.10278754708
manual: 7.709ms
using wasm : 156581.10278754708
wasm: 0.287ms

Commencez par reproduire la comparaison des temps avec require("../func/haversine") et require("haversinecalc"), puis consultez l’issue wasm-bindgen liée pour le contexte de l’initialisation du module. Un résultat utile serait une réponse documentée expliquant le comportement pertinent du chargement des modules de Node.js et comment mesurer séparément l’initialisation et les appels répétés.
