Why does my Discord.js bot take more than five minutes to respond on a server with less than 500 users?

I've just developed a bot for adding roles to a user who starts streaming on my server. When I tested the bot on a isolated server with only a few channels and users the bot responded instantly. But now I have set up my bot on my primary Discord server with roughly 25 channels and about ~500 users and now the response time is more than five minutes before I see it add or remove a role.

I am connecting via FIOS gigabit and running on a I9 with DDR4 4266MHz RAM.

When I first start the node server I notice the delay is much less, however still very slow responses of around a minute or two before it adds or removes the roles. If I allow the server to run for ten minutes then the response time is around five minutes before it adds a role. I do not know if it continues to get worse over time. But what could be causing this delay? I see my user status change to streaming (purple dot) in the online users list immediately, but my discord bot is not aware of this for a very long time!

This is my code, I have tried my best to optimize it but I've only been learning Discord.js for about a week and am still very unfamiliar with it:

// require the discord.js module
const Discord = require('discord.js');

// create a new Discord client
const client = new Discord.Client();

let role = '';

client.once('ready', () => {
    const myGuild = client.guilds.cache.get('123456789123456789');
    role = myGuild.roles.cache.find(role => role.name === 'streaming');

    console.log('Ready!');
});

client.on("presenceUpdate", (oldPresence, newPresence) => {
    
    if (!newPresence.activities){ return false; }
    
    newPresence.activities.forEach(activity => {
        if (activity.type == "STREAMING") {
            //console.log(`${newPresence.user.tag} is streaming at ${activity.url}.`);
            newPresence.member.roles.add(role)
        } else {
            newPresence.member.roles.remove(role)
        };
    });
    
});

// login to Discord with your app's token
client.login('123456789123456789.123456789.123456789123456789');

Can someone please explain why my bot is becoming so sluggish? It is almost unusable and kind of discouraging.

The default maxListeners is set to 10 and it may be worth exploring setting that value higher.

Additionally, I am curious if there is a memory leak on your application. It sounds like it from the sluggishness that is experienced over time.

Try using a profiling tool like Clinic.js to monitor the state of the application over time.
