Slow rendering between version v1.2.0 and v1.3.0

[Toutenkit]

After encountering the problem "admin file_get_contents() permission denied"
SOLVED >1.7.34 - admin file_get_contents() permission denied error - windows and php 8.18 and below · Issue #2299 · getgrav/grav-plugin-admin · GitHub
I upgraded my local server to the latest version of PHP 7.4.[x] & 8.10 and no results so I went back to older versions which work fine

Windows 10
Wampserver 3.1.9 64bit
PHP 7.3.9 ( >= 7.4.[x] pas supporté par Wampserveur)
Apache 2.4.39

I tried to reproduce the error and found a problem with the Flex Objects plugin
I don't know if the problem could be related to the bug "admin file_get_contents() permission denied" (Slow rendering before error)

On fresh installation
Tested each in turn and did exactly the same on all three versions

Test 1

Flex Objects v1.2.0

Grav: page rendering	v1.7.33	v1.7.34	v1.7.35
/pages/typography	Fast (2s)	Very long (20s)	Very long (20s)
/pages	Fast (2s)	Very long (20s)	Very long (20s)

Test 2

Flex Objects v1.3.0

I have disabled the Flex Objects plugin

Grav: page rendering	v1.7.33	v1.7.34	v1.7.35
/pages/typography	Fast (2s)	Fast (2s)	Fast (2s)
/pages	Fast (2s)	Fast (2s)	Fast (2s)

Test 3

Flex Objects v1.3.0

\config\plugins\flex-objects.yaml
Disabled for pages (Admin)
directories:
    2: 'blueprints://flex-objects/user-accounts.yaml'
    3: 'blueprints://flex-objects/user-groups.yaml'

Grav: page rendering	v1.7.33	v1.7.34	v1.7.35
/pages/typography	Fast (2.8s)	Fast (2.9s)	Fast (2.7s)
/pages	Fast (2s)	Fast (2s)	Fast (2s)

We have tried to replicate the issue, but we've had no success. The page load is fast with both older and newer versions, there's no meaningful difference between them. With and without cache. How many pages do you have? Have you installed any plugins?

[Toutenkit]

I did the test with a new installation without any modification or addition.

---

I redid the test by taking the "Network" tab
I made a mistake in the position on versions of the Flex Object in the previous post

New installation of Grav without any modification. Grav download from Github.
On Chrome I did not check in Network "disable cache".
I make a first tour of the backoff by going to save the page "Typography", to make cache
Then I visit each page while waiting for another one to be finished

(New installation of Windows 10 on new hard disk)

Problem:
Page rendering and page saving are very long with the Flex Objects plugin enabled

If you need a specific test, let me know
