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
