Is my Socket.io application consuming excessive bandwidth? What might be causing this issue?

Upon reviewing my AWS billing report, I noticed an excessive data transfer of 495.385 GB on my socket.io application running on the EC2 instance. This amount seems too high for a small experimental website like mine. Could this be due to inefficient code implementation?

I have 20 .html files displaying various exchange rate charts that all request data from the socket using the following code snippet:

// Insert code snippet here

On the server side, I have different socket.emit functions for each currency. The continuous emission of sockets raises concerns about the high bandwidth usage and possibly inefficient coding practices.

Is it possible that multiple socket emissions are causing the high data transfers? If so, how can I optimize this code to reduce data consumption?

The goal is to enhance code efficiency and minimize data usage in my application.

Answer â„–1

Is the high bandwidth usage due to multiple sockets emitting data?

Your server is sending out numerous io.sockets.emit() calls (at least 22) every 10 seconds to all connected clients. This constant flow of data can consume significant bandwidth, especially if the website is left open continuously (equating to 190,080 emits per day with just one browser window).

Does it only send data to connected clients? Would reducing socket emits and intervals help optimize this?

If so, are there ways to improve the efficiency of this code?

Yes, data is emitted specifically to connected clients. One approach to enhance efficiency would be to consolidate the emit calls into a single combined emit rather than multiple separate ones. Additionally, consider minimizing the size of payloads by optimizing JSON data format—shortening object property names can significantly decrease payload size.

Furthermore, you may want to explore lengthening the interval between data transmissions based on client activity levels. You could implement a system that adjusts transmission frequency depending on user interaction or page visibility. By organizing connections into active and inactive groups, you can tailor data delivery accordingly, transmitting more frequently to active users and less often to inactive ones.

To implement variable interval functionality, new connections can be initially assigned to the "active" room. Clients can indicate their current state to the server, allowing for dynamic adjustment of data transmission frequency. A UI notification can inform users when the page is inactive, prompting them to manually refresh or automatically activate the page upon detecting activity.
