Can't recall the exact parameter off the top of my head, but there is
one that can be set to intentionally force a delay on the application of
logs to the standby.  It is done to give you a chance to prevent logical
corruption/user error (e.g. accidental drop/delete) from being
propagated to the standby if you desire to do so.  You might want to
look up the parameter and confirm if it's set or not.  If that's not the
cause, then check the wait events for the log apply session and see
where it's spending it's time.

Regards,
Brandon
