Re: [EXTERNAL] Re: OEL versus RHEL

Oracle Unbreakable Enterprise Kernel (UEK) is optimized for IO intensive workloads and uses newer Linux kernel release.

Watch the "Benchmarking the Oracle Unbreakable Enterprise Kernel" webinar here:
https://go.oracle.com/LP=97097?elqCampaignId=261059#On-Demand-Webinars

Also read through the latest UEK release notes to see the notable differences between UEK and RedHat Compatible Kernel (RHCK): https://blogs.oracle.com/linux/post/announcing-the-unbreakable-enterprise-kernel-release-6-for-oracle-linux https://docs.oracle.com/en/operating-systems/uek/7/relnotes7.0/uek7.0-NewFeaturesandChanges.html#uek-features

You can run Oracle Linux with either UEK or RHCK, both are free.
