How fast is a WebSocket?

Plain WebSocket can be up to 3.7 times as fast to receive a message from the server compared to Socket.IO and 1.7 times as fast compared to SockJS. Plain WebSocket scales well in terms of response time and memory requirement with higher concurrency levels.

How much bandwidth does a WebSocket use?

The average of bandwidth usage is 478KB for polling method, and 91KB for web socket method in web based.

Are WebSockets still used?

For now, I think there are plenty of applications already using Websocket. And there are many frameworks developed for Websockets in almost all the programming languages. They are very matured as well. Only caveat developers may think of Websocket is that, the fact that it's not HTTP.

Why are WebSockets so fast?

Websocket is said to be faster than http because it provides full duplex communication. So, both client and server can communicate at the same time.

Why not to use WebSockets?

Avoid using WebSockets if only a small number of messages will be sent or if the messaging is very infrequent. Unless the client must quickly receive or act upon updates, maintaining the open connection may be an unnecessary waste of resources.

How do you test Socket performance?

Since Socket.IO has its own protocol, including handshake, heartbeats and custom packet encoding, the easiest way to load test your Socket.IO server is to use the Socket.IO client library and create a lot of clients. There are two classic solutions to do this: using Artillery. or manually manage the clients.

Is TCP faster than WebSocket?

WebSockets performs quite well, with an average round trip time of about 20 microseconds (0.02 milliseconds), but straight up TCP still beats it handily, with an average round trip time of about 2 microseconds (0.002 milliseconds), an order of magnitude less.

How much RAM does a WebSocket use?

With websockets' defaults, on the server side, a single connections uses 70 KiB of memory.

Are WebSockets faster than API?

WebSockets have a low overhead per message. They're ideal for use cases that require low-latency, high-frequency communication. REST APIs have a higher message overhead compared to WebSockets. They're best suited for use cases where you want to create, retrieve, delete, or update resources.

Is WebRTC faster than WebSockets?

WebRTC is known to offer peer-to-peer (P2P) communication capabilities for mobile and browser apps using the UDP whereas WebSockets establishes a client-server connection with the aid of TCP protocol. And so, WebRTCs are known to be considerably faster than WebSockets.

Is Socket.IO faster than WebSockets?

On the other hand, for more complex use cases, such as a chat app, Socket.IO is a superior alternative, as it allows you to move faster than plain WebSockets.

What is WebSocket latency?

If the original message is small in size and socket is not throttled, the client can echo the same message back to server. The server can then find the roundtrip latency by calculating the time elapsed between sending of original message and receiving the echo'd message. Dividing this by 2 gives one way latency.

Is WSS faster than HTTP?

As is clear from the table, for our use case Websocket is expected to be about 5-7 times faster than plain HTTP. 3. Security: From security perspective, both HTTP (via HTTPS) and Websockets via (WSS) provide the TLS layer so there is not much to choose from.
