I think they offer you a choice of kernels.
Their own kernel has performance enhancements.

It's also supposed to be cheaper in maintenance than RHEL.
But AFAIK, it's a re-engineering of RHEL in the same way CentOS is.
Just with commercial support (and geared towards running Oracle stuff).

I just looked and at the most basic level (patches only) it costs
94€/year/system.

Does anybody know how fast they implement the fixes from upstream?
