How-To: Determine CPU Speed on Linux

How To
I’ve been trying to work out how fast a server that I maintain is (in Mhz). The simplest way to do this is to follow these instructions:
Enter the following command:
dmidecode | grep “Current Speed” | head -n 1
And you should receive output like this:
Current Speed: 3400 MHz

You could also do the following:
sudo dmidecode -s processor-frequency
Also note that Current Speed and Max Speed may be different

…Or you might try this:
dmesg |grep -i “MHz processor”
…and get an answer like this:
Detected 2599.954 MHz processor.
