Hi @yohan17797,

If you are running a community website with Gwangi, the only required plugins are the following:

– BuddyPress (for the community features)
– Grimlock (our custom template engine)
– Grimlock for BuddyPress (BuddyPress customizations)
– Kirki Toolkit (dependency for Grimlock)
– Easy Custom Sidebar (for sections pages like homepage, etc…)

If you install only these plugins, you will have the bare minimum features to run your website.

Also, I suggest that you read the following reply in the topic that you linked, to get some advice on how to improve performance:

Hope this helps.
