I'm currently using version 4.4.2 and I am came across an issue while using the
ratelimit module with the FEEDBACK algorithm.
Checking the ratelimit.c to see how the cpu load value is calculated I saw that
the module parses only the line corresponding to the overall CPU usage in the
"/proc/stat" file.
First, the module calculates the amount of CPU that is idle, in percentage.
But, when the module is going to calculate the percentage of the overall CPU
usage, it first divides the idle value obtained previously by the number of CPU
cores, and then subtracts this value from 1.
The mistake here seems to be the division by the number of CPU cores, because
the overall porcentage retrieved from the /proc/stat file is already in the
range from 0-100, regardless of the number of CPU cores
