Anyone who implimented ZTA, hows network performance?

I'm going thorugh CSA CCZT course and a question came to mind. Since ZTA trusts nothing and verifies everything, this means every initial request to a resource is verified, authorized, authenticated and timed. Has anyone implemented some form of ZTA and noticed a change in network performance because every request now has to be authenticated?
