I'm facing an annoying problem with Docker using a php:7.4.12-apache-buster image and WordPress.
I mounted source code to Docker container and everything works properly except that after some minutes of inactivity first refresh of the host browser takes over 10s, subsequent refreshes are 290ms but again, after some inactivity minutes, the first request is slow and subsequent ones are fast.
I'm facing this for over a year trying to understand what happens, I saw some people saying that have a kind of sleep configuration on the container and others saying that it's a DNS problem but, I tried barely everything without success including docker-sync.
That's is my docker setup configuration files.

All this is happening running Docker for Mac in OS X Mojave 10.14.6 on a local environment.
Any insight will be very helpful.
