Hello guys,
Did anyone noticed how green CentOS 6 is compared to the previous release? I've been running a couple of "CentOS 6" VMs (on our vSphere environment) for the last couple of weeks and noticed a BIG difference when it comes to CPU usage when the VM is completely idle. I would like to share what I've seen in our environment:
PfSense 2.0 (FreeBSD) VM: 40 Mhz CentOS 5.7 VM: 60 Mhz CentOS 6.2 VM: 5 Mhz
This is really wonderful. They did a great job with RHEL6 and I'm curious what was changed in order to accomplish this.
Regards, Jorge
