I would like to install a core set of plugins that I will use in the next 6-12 months in a multisite install. The question is if I have plugins network enabled and activated but don't use the features at that time what overhead performance and server resources penalty occurs for carrying the dead weight until I want to use it?
I am making an assumption that if I install and activate the plugin at the beginning and say use 1 feature of that plugin as a place holder then when I want to really use the full features of those plugins I won't run into the problem of inserting the features after 6-12 months of activity. As an example membership 2 pro. I might offer memberships latter but not to start and just make all content available to anyone. Then in the future start adding controlled content for real memberships. There are several plugins that I will want to use but not sure when I will use them.
So is there a hit on performance etc for activating unused plugins ?
Is my assumption correct that if I think I will use it in the future go ahead and activated and that will be easier then activating it after 6 months of activity on the site?
Are there some plugins not to do this and some that it would be ok ?
