AQRT of R820 test environment

Figure 6.

CPU Utilization of R820 test environment

Figure 7.

Figure 6demonstrates that all VM are scaling up to 5200 userload simultaneously with SLA below 2 sec.
Figure 7 shows that average CPU utilization across all VMs is ~70% while they are supporting 5200 users.
Also it can be noted that there is roughly ~24% IO wait time, means that VM CPU resources are waiting
for the storage system to provide the data and there is storage bottleneck.

We may conclude from Figures 6 and 7 that all four VMs support 5200 userload with 70% CPU
utilization.
