[split] Real time? [CodeIgniter 4 Important Features]

No, that is exactly the opposite of what I'm saying.

You're equating effort to result, and also comparing a comparatively low-level (it being a language; PHP) server-side technology to a framework that has both server-side and client-side components.

Neither makes sense.

The client is irrelevant since PHP only runs on the server. Regardless of which stack you use on the server the client will always be JS.

Which is why it's an unfair comparison.
I assumed you were talking about NodeJS from the get-go; you mentioned sockets.io later ...

Due to it's design Node will always be more efficient at handling high throughput.

No, it is simply far easier to use NodeJS for similar purposes, because that's what it is designed for.
Easier to work with by design, not the same thing as more efficient.

If it wasn't why would every single real-time framework use it?

I just answered that, but here's some extra info from a familiar source:
