Hi,
You need more than 1 QGIS Server process running on your server to get a
responsive Web client.
I think you have more than 1 QGIS Server process available to response
to lizmap web client requests to QGIS Server.
The number of available QGIS Server processes depend on the server you
use for QGIS Server (apache, nginx, or py-qgis-server) and the interface
used for QGIS Server (fcgi or py-qgis-server).
Then for the lizmap server cache configuration, it has to be done in the
Lizmap Desktop plugin for each layer you want to cache on the server.
You can find the detail here
https://docs.lizmap.com/current/en/publish/configuration/optimization.html#server-side
Regards,
René-Luc
