As I've been saying (in my opinion) if you're unsure, lock. However if you are sure that not locking will not cause any issues, then its only better performance to drop needless code. Most people would agree that many (if not all) session reads (for example) don't need to be locked (depending on the application of course). For example consider the common practice of placing a "LastAccessed" timestamp in your session scope. This variable is updated with the current when a user makes a request. If two templates attempt to update the value at the same time it doesn't matter (at least to my application): the time is only used to determine if a session is "stale" so either time is fine as they're both essentially the same. Personally I wouldn't lock that write in CFMX (in previous versions I would). To me it's always about the current situation. I agree in general that session data generally needs to be locked, but each situation presents different circumstances.
