I am sure there is a better way to do this but since I was impatient.

Confirm that your Cores are set too low
Code:
cat /proc/cpuinfo |grep "MHz"
Output:
cpu MHz : 1600.000
cpu MHz : 1600.000
cpu MHz : 1600.000
cpu MHz : 1600.000
cpu MHz : 1600.000
cpu MHz : 1600.000
cpu MHz : 1600.000
cpu MHz : 1600.000



Install CPUFreq Untilities
Code:
sudo apt-get install cpufrequtils
Attempt to set the governor to "Performance", which in theory should maximize the cores.
Code:
sudo cpufreq-set -r -g performance
Check
Code:
cat /proc/cpuinfo |grep "MHz"
If Successful, then you are done. If not you may have to set the core speed manually.
Print Supported CPU Steps
Code:
cpufreq-info|grep "stats"
Manually set each core to the highest step (3.30Ghz in our case) -c is the thread we are changing, -f is the frequency.
Code:
sudo cpufreq-set -c 0 -f 3.30Ghz
Code:
sudo cpufreq-set -c 1 -f 3.30Ghz
Code:
sudo cpufreq-set -c 2 -f 3.30Ghz
Code:
sudo cpufreq-set -c 3 -f 3.30Ghz
Code:
sudo cpufreq-set -c 4 -f 3.30Ghz
Code:
sudo cpufreq-set -c 5 -f 3.30Ghz
Code:
sudo cpufreq-set -c 6 -f 3.30Ghz
Code:
sudo cpufreq-set -c 7 -f 3.30Ghz
Check
Code:
cat /proc/cpuinfo |grep "MHz"
Output:
cpu MHz : 3300.000
cpu MHz : 3300.000
cpu MHz : 3300.000
cpu MHz : 3300.000
cpu MHz : 3300.000
cpu MHz : 3300.000
cpu MHz : 3300.000
cpu MHz : 3300.000

If any of you have recently switched to running your CS:GO servers on Ubuntu 13.04 and have noticed drastically lessened server performance and high variance rates, this is a fix you should implement. Running this fix allowed my servers to go from >4.0 variance with only 20 (128-tick) slots full to having <1.0 variance with 80 (128-tick) slots full.

Some how our servers reset themselves to 1600 Mhz.

Apparently, restarting the server machine sets the MHz back to 1600. It just so happens that the other day I realized the server wasn't restarting nightly as suspected, and I fixed that, and inadvertantly broke our servers.

Any idea how to make it happen on restart? Do I just need to add those six commands for @reboot?

I attempted @reboot root cpufreq-set -r -g performance (as that command was working fine with sudo), with no luck.

I attempted @reboot root cpufreq-set -c 0 -f 3.30Ghz. This also did not work.

Any advice on reinitializing these commands on reboot?

I set the minimum frequency the governor can use to 3.3Ghz
Code:
cpufreq-set -r -d 3.30Ghz

Some how it got reset today. Even though I restarted it a couple times after you made the fix, today it is back to running at 1.6GHz.
