The following graphs show the CPU utilization across the three hosts during the testing. CPU usage with all VMs powered on was approximately 7.3 percent before the test started.
During the steady-state phase, an average CPU utilization of 85 percent was recorded. This value is below the pass/fail threshold that we set for average CPU utilization (see Table 3). To maintain good EUE, do not exceed this threshold. You can load more user sessions while exceeding this threshold for CPU, but you might experience a degradation in user experience.
As shown in the following figure, the CPU readiness was well below the 5 percent threshold that was set:
The average steady-state CPU core utilization across the three hosts was 61 percent, as shown in the following figure:
The team observed no memory constraints during the testing on the compute hosts. Out of 768 GB of available memory per node, the compute host reached a maximum consumed memory of 678 GB and a steady-state average of 677 GB. Active memory usage reached a maximum active memory of 399 GB and recorded a steady-state average memory of 234 GB. There was no memory ballooning or swapping on the hosts.
Network bandwidth was not an issue during the testing. The network usage recorded a steady-state average of 2847 Mbps. The busiest period for network traffic was during Logoff Phase when a peak value of 5000 Mbps was recorded.
The following figure shows the network usage:
Cluster IOPS reached a maximum value of 6404 for read IOPS and 4384 for write IOPS during the steady-state phase. The average steady-state IOPS metric was 2465.
Cluster disk latency reached a maximum read latency of 0.868 milliseconds and a maximum write latency of 1.002 milliseconds during the steady-state phase. The average steady-state latency was 0.52 milliseconds.
The Login Enterprise EUX score was 7.6/10 and the VSImax was >465, which means that VSImax was not reached during this test and that it would be possible to run more sessions with this configuration. For more information, see this Login Enterprise EUX Score – Login VSI article.
