Permissive mode will warn but still allow all actions that would otherwise be blocked in enforcing mode. When you disable SELinux and then later re-enable it, the whole file system will need to be relabeled at boot, and this is probably what took the time on your system. Switching between permissive and enforcing modes avoids this.
