VMWare, CPU average

I took two samples from esxtop under heavy load on a single VM on a rather large machine

The first one is esxtop (CPU)

 4:35:08pm up 31 min, 772 worlds, 1 VMs, 10 vCPUs; CPU load average: 0.17, 0.12, 0.11

Notice the CPU load average

In the second (esxtop -N), it never actually changes from0.02, even while the CPU load average grows in the esxtop (CPU) command

Is this normal, or does it reflect a problem of some sort

They are averages for last 5, 10 and 15 minutes.
So unless the CPUs gets to eat some pepper it will remain there.
