Hi sir
Thanks for explanation. Really felt good that someone has gone through the issue.
But, the CPU doesn't show as maxed out, on jmeter and aws console the web instances show it has reached max 70% and 25% respectvely.

What could be the reason?

If you require additional information to address my issue please let me know.
