Hi, I’m working on a website with almost 5000 articles. I’m still on development mode, so I turned off the Cache.
The problem is that the home page take about a minute to load.
I turned on the debug mode and you can check the results yourself.For example… mod_jacontentslider take about 25 seconds and 100MB to load.
If I turn the Cache ON everything is fine, but I can not operate in this way… there must be a problem somewhere…
Thank you for you support
ClaudioOk, I found something…
the mod_jacontentslider fire the following query that returns all the 5000 articles and take about 15 seconds and 100MB.
I attach a screenshot of my backend module configuration
I tried to upgrade the module to the last version 2.5.6, but nothing changed
