What's the impact of not running with Websockets

[adamgins]

@arunoda this sounds really interesting. I noticed that you are not running with Websockets. Anyway, I was wondering if you have any high-level guidance on what sort of performance impact could we expect on falling back to HTTP (vs TCP/Websockets), please?

We are not running with WS because of the SSL. We use Cloudflare for SSL and they don't support WS yet. So, we turned off WS.

It's a bit slower than WS for realtime stuff. But for Kadira, we found it's okay to turn off WS. There was not much latency issues.

And cluster works well with this situation too. Actually, it doesn't differentiate.

Thanks. Any rule of thumb/rough guide on what over head HTTP would put on your system vs websockets?

From the server perspective, it won't does anything different. (We haven't done any test yet).
But I've seen it reduces the server load for one of my friend. His app is being used in places where connection is very poor and WS is not available much.

So, WS gets re-connected everytime. That re-subscribe everything. But once he turned off WS, this issue was not there and server load gets reduced.
