After our upgrade from 7.0.2 CE GA3 to 7.0.3 CE GA4, we encounter big latencies when accessing to Control Panel pages.

When monitoring network calls under chrome, we concluded that these latencies are related to to url prefixed with manage?p_p_id

Steps to reproduce -updated:

1. Start bundle with clean database
2. Login and go to control panel > web content
3. Monitor the time in browser's developer tool

Expected result:
No big latency time while accessing the page.

Actual result:
Big latency time while accessing the page, it only happens at the first time accessing to the page.
