Server requirements/overhead for FluentCommunity

Before I buy and install, I'm curious if there are any minimum server requirements?

I have an existing site that I would like to add it too. This site is already running FluentCRM Pro, FluentForms Pro, and FluentBooking Pro so I'm encouraged by the compatibility. But i'm afraid that it might slow down my site.

Will FluentCommunity add much overhead or increased load to an existing site? Should FluentCommunity be installed on a separate WP install?

I'm excited for the potential. Anyone with real-world experience that can offer some thoughts? Thank you for any insight/guidance you can provide.
