> JWTs are inefficient for performance and are bloated in their data structure and have a performance hit when you parse the token to extract its properties compared with the same operation in other alternatives (simple session cookie require zero parsing and thus is faster) While a session ID doesn't require parsing, it is useless on it's own; a fairer comparison would be: time to validate and parse/deserialize a JWT vs time to retrieve session data from the backing store (e.g. database, redis).
