How

Check your instance’s cpu.

$ lscpu

CPU(s):                2
On-line CPU(s) list:   0,1
Thread(s) per core:    2
Core(s) per socket:    1
Socket(s):             1

In this case, this cpu work normal until load average 2.00 which is referred from below:

While a load of 1 can mean approximately 100% resource usage on a single processor system, such systems are practically non-existent today. Unless you haven’t upgraded your system in over a decade, your system should run on a multi-core processor.

For a dual-core processor, a load of 1 means that 1 core was 100% idle. This translates to approximately 50% CPU usage. Similarly, it would represent 25% CPU usage for a quad-core processor.
