Reproduction

Create a new Nuxt 3 app, build it and run the built app.

Describe the bug

I noticed that the production app is constantly increasing the amount of used memory. So, I made measurements with Chrome allocation instrumentation on the timeline and made 10000 requests to this app via ab (Apache HTTP server benchmarking tool).

Results:

Thus, it showed a large amount of data that remains even after their use. Namely, the potential source of the problem is metaConfig.globalMeta.

So, after that, I commented this line.

And made the same measurements again.

Results:

And the problem disappeared. The selected size decreased from 46.3 MB to 9.1 MB.

Can you look at this, please?

Thanks - really appreciate it.

I'm closing to track in #13397 but this debugging should be hugely helpful in resolving.
