Getting Cold start latency of 5+ seconds even after using the preferRest option for firebase-admin

I was getting a cold start latency of 5+ seconds while using firestore database. I came across this age old issue- https://issuetracker.google.com/issues/158014637 and the solution here- https://github.com/firebase/firebase-admin-node/pull/1901 but even after implementing the solution as mentioned, I am still getting a latency of 5-6 seconds.

"firebase-admin": "^11.8.0" is the only dependencies I have.

Please find below my code snippet- ` const { initializeApp } = require("firebase-admin/app");

const { initializeFirestore } = require("firebase-admin/firestore");

if (!isAlreadyInitialized) {
  const app = initializeApp();
  db = initializeFirestore(app, { preferRest: true });
  isAlreadyInitialized = true;
 }

const query = db.collection("apps").where("apiKey", "==", apiKey);

const querySnapshot = await query.get();

//At this point I am returning a response.`

I am expecting a cold start latency of maximum 1 second but I am getting different latencies at different times going all the way upto 5-7 seconds as well. Can someone please help me on this?

HKST
