Rather than disabling, you can put SELinux in permissive mode to
troubleshoot. 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.
