Server Load with CPU Usage

Hi,
I'm running a VM with access to 4 Cores of E5-2620 v2 (2.1 GHz x 4). Recently, having problem with High Load. But, I can't understand how the CPU being 90%+ Idle, Load goes to 3.5+ ??
Can anyone explain me the internal factors ??

Nginx looks to be in sleep. Most likely cause is blocking on disk IO. Any disk issues?
Err. I'm pretty sure it's CPU "traffic". Correct me if I'm wrong!
I ran iotop & monitored for 5 Minutes. Total Disk Read Never Crossed 10 mbps in that time-frame & Total Disk Write never Crossed 4 mbps in that duration. Is that Normal or I'm using much ??
CPU load is essentially a running queue of CPU "tasks". The longer the list, the higher the CPU load. He meant that IO can prevent tasks from being processed on the CPU - thus queuing up.
The code used is pretty simple:
So you do have some bottleneck somewhere. I doubt the IO, else you're running on a flash drive.
I've monitored it when the Server Load was remaining between 0.50-0.90. I've to keep My Eyes open when it goes above 4.
