Bad performance using nested and populate together

[MattPryze]

Sending a REST API request in the format /api/menus/1?nested&populate=* leads to some pretty poor performance.

Getting a menu with about 100 items takes around 1000ms each time.

I'm using SQLite for my database and would rather not change it as all other requests are running fast.

I tried using the REST cache plugin, but it didn't seem to have any effect. I suppose I may be configuring it incorrectly?

Is this the expected behavior of this call? Is there a better way to quickly grab my nested menu on page load?

This may not be the fault of this plugin I'm learning. Looks like any request I make to a json field of this size, even outside this plugin, has the same speed. But if I format the field as string and just parse it after receiving it, it's only a few ms.
