Need help to understand if my CPU is overloaded.

model name: Intel(R) Xeon(R) CPU E5-4657L v2 @ 2.40GHz

$ less /proc/cpuinfo | grep processor
processor       : 0
processor       : 1
processor       : 2
processor       : 3

$ less /proc/cpuinfo | grep "core id" | sort|uniq | wc -l 
4

$ less /proc/cpuinfo | grep "physical id" | sort|uniq | wc -l
1

siblings : 4

Load avg is 8.97, 9.33, 9.57 (top command output during the peak hour).

Yes, your CPU is overloaded.

The numbers 8.97, 9.33, 9.57 tell how many processes on average were trying to use you CPU during the last 1, 5 and 15 minutes respectively.

Your CPU can handle up to 4 processes at a time, so the number 4 would mean full load; 2 – 50% idle; 9 (as in your case) – that there were on average 9 - 4 = 5 processes at any given time (during the respective period) waiting for the CPU. This means an overload by more than 100%.

I gave this answer to explicitly cover your case. In general your question duplicates this one.
