I use some plugins which I am pretty sure are not used when I am not logged in & accordingly not a cause of slowness for anyone but me (for example Media Library Assistant)
I can obviously just ignore the data given relating to that plug-in (though I may not be right in assuming it does nothing for a non-logged in user: it could actually be doing something I don't know about).
It would be great to assess my site with P3 as if I am not logged in
Is this possible?
With thanks in anticipation
