Why Firebase cloud functions are slow. 1 second to complete

[CiprianGabor]

Why my Firebase cloud functions are slow. I have tested a simple function and it takes more than 1 second every time.

this is my code in Kotlin:

coroutineScope.launch(Dispatchers.IO) {
    val timeTaken = measureTimeMillis {
        currentAndroidVersion =
            loginViewModel.repo.checkAndroidVersion(lastUpdateDate)
    }
    println("checkAndroidVersion took $timeTaken ms to execute")
}

this usually prints:

checkAndroidVersion took 1394 ms to execute

checkAndroidVersion took 1028 ms to execute

KMM repo:

val functions = Firebase.functions("europe-central2")

suspend fun checkAndroidVersion(version: String): String{
    return functions.httpsCallable("checkAndroidVersion").invoke(version).data<String>()
}

cloud function:

exports.checkAndroidVersion =
onCall({region: "europe-central2"}, (request) => {
  logger.info("current user version = "+request.data, {structuredData: true});
  const version = request.data;
  if (version != "15/10/2024") {
    return version;
  }
  return "updated";
});

these are my dependencies:

implementation("dev.gitlive:firebase-firestore:1.10.4")
implementation("dev.gitlive:firebase-common:1.10.4")
implementation("dev.gitlive:firebase-auth:1.10.4")
implementation("dev.gitlive:firebase-functions:1.10.4")
