Many were hesitant to sacrifice site speed for the added layer of security if they felt like they didn’t need it. Google made SSL use a ranking factor way back in 2014, and since Chrome 68, a “Not Secure” warning appears next to the URL of sites that aren’t using HTTPS. So what’s the truth? Is SSL slow?
