Would the average schmoe like me actually gain anything by running UEK over the standard Redhat kernel if I'm not running stuff like the Oracle database? > Oracle UEK kernel is newer (based on 5.4.17 I think), probably support more hardware. Also, Oracle UEK kernel supports BTRFS filesystem, that Redhat don't even allow you to use it. I use UEK because this.
