Last week, I ordered a dedicated server from OVH at a surprisingly affordable rate of US$14.40 per month. The KImsufi KS-LE-C comes with impressive specifications that caught my attention.
The advertised CPU power of 3.7 GHz / 3.9 GHz seemed promising. However, after running initial tests with yabs, I noticed the speed was capped at 2.4 GHz, despite having the same processor model. Something wasn't quite right.
Solution
Thanks to helpful guidance from the forum community, I learned that the CPU needed to be "unlocked." Here's how to achieve the full processor potential:
First, install cpupower from the linux-tools-generic package
sudo apt install linux-tools-generic
Before making any changes, document your current CPU frequency
sudo cat /proc/cpuinfo
Unlock the CPU's full power by setting the governor to performance mode
sudo cpupower frequency-set --governor performance
After Unlocked
After implementing these changes, the CPU speed increased from 2.4 GHz to its advertised 3.7 GHz. A simple fix for a significant performance boost!
For comparison purpose, here another YABS. ColoCrossing KVM VPS with Intel E5 processor.
