CentOS 7 vs 6 performance?

[Magistar]

I am trying to find performance benchmarks on CentOS 7 vs CentOS 6. So far I only found something really old that compares RC with an old version of CentOS 6. Does anyone know of any more recent tests?

I/O scheduler by default is more faster.

In RHEL 7, the deadline I/O scheduler is the default I/O scheduler for all block devices except SATA disks. For SATA disk, the default I/O scheduler is cfq.

systemd it's much faster.

FirewallD better than iptables/netfilter.

The new XFS filesystem it's much faster.

Everything is much more optimized.
