How is container CPU calculated ?

Kondense resize each container CPU every second with the following steps.

1. Calculate average CPU usage

Kondense calculate the average CPU usage over the last INTERVAL seconds. By default, INTERVAL is 6 seconds.

2. Calculate new CPU

We need the TARGET_AVG to calculate the new CPU. By default, TARGET_AVG is 0.8 so 80%.

new_cpu = average_cpu / TARGET_AVG

2.1 If new_cpu is smaller than current CPU limit

If new_cpu is smaller than the current CPU limit, we just patch CPU limit with this new_cpu.

2.2 If new_cpu is bigger than current CPU limit

If new_cpu is higher than the current CPU limit, we exponentially increase new_cpu with this formula:

new_cpu = new_cpu + (new_cpu * coeff)²

The bigger the coeff, the stronger Kondense will increase the CPU. We patch the CPU limit with this new_cpu.
