"Faster" is ambiguous, and there are a lot of factors involved. HTTPS isn't just "add encryption", it's also "do more at once and don't block as much" because HTTP/2 (a faster version of HTTP) only uses HTTPS in practice. You can discuss "HTTPS performance" in a purist way that makes it look slower than plain HTTP, but in practice (the only way that matters) HTTPS is faster than HTTP.
