Slow performance while having large array of facts.

I have integrated json-rules-engine with a project I am working on and the performance seems much slower than I would expect. I'm using the package to do a simple lookup at another set of facts.

```
const lookupFacts = [
{ col1: '', col2: '', col3: ''},
{ col1: '', col2: '', col3: ''},
{ col1: '', col2: '', col3: ''}
]

const filterRule = {
conditions: {
all: [
{
path: "$.col1",
fact: "fact",
value: {
path: "$.col1",
fact: "lookup"
},
operator: "equal"
},
{
path: "$.col2",
fact: "data",
value: {
path: "$.col2",
fact: "lookup"
},
operator: "equal"
},
{
path: "$.col3",
fact: "data",
value: {
path: "$.col3",
fact: "lookup"
},
operator: "equal"
}
],
event: {
type: 'filter-event'
}
}
}

const engine = new require('json-rules-engine').Engine()

let filteredMatchs = await Promise.all(lookupFacts.map((lookup) => {
return engine.run({ lookup, data })
.then(({ events }) => events.length > 0 ? lookup : false)
.catch((err) => false)
}))
.then((values) => values.filter((value) => value))
```

In my case, the lookupfacts array seems to contain about 80000 entries and it takes around 30000 ms to complete. Whereas doing the same comparison using simple javascript code takes about 10-15 ms only.

I will only be not be having any dynamic data in the flow. Is there a way to improve performance?

Thanks

Aucun fichier du dépôt ni aucun test n’est indiqué. Commencez par reproduire le benchmark fourni autour de Engine.run avec 80 000 entrées et comparez-le avec la recherche JavaScript simple ; le travail doit aboutir à une amélioration mesurée et exploitable des performances, ou à une limitation clairement documentée.
