What refresh rate is recommended for an AJAX chat to ensure optimal performance?

How can we determine the optimal refresh rate that maintains quality while preventing server crashes?

Answer â„–1

Avoid constantly checking for new messages (the cost of continuous refreshing will become too high as your system scales); instead, set up the server to send new messages directly to the AJAX client.

For more information, refer to Comet (persistent HTTP request).

Answer â„–2

The frequency of message responses depends on various factors such as response time, server capacity, and bandwidth. In my opinion, sending a response every 500ms after completing a request would create a smooth communication experience.

It is important to start the timer only after the previous request has been completed to avoid queuing up and overlapping of messages due to latency issues.

My recommendation is to incorporate passing datetime information back and forth between the client and server. This involves sending the timestamp of the last message from the server to the client and then returning it when requesting new messages. By doing this, you can ensure that only relevant chat data is exchanged, minimizing unnecessary traffic.
