Hello All,
I noticed something on the memory usage behavior on esxi 5.0 and wanted to check if this is expected behavior and if so, why do you think it happens
We are running a load test on some guest VMs and vCenter performance chart shows (real time) shows the right usage. However after the load test is done, according the real time performance chart, the memory utilization does not come down immediately. It takes around 15 minutes for the memory usage to come down, as per the real time performance chart. However when we check inside the guest OS, it has released all the memory and is not showing any usage.
Is this behavior normal? Why does the real time performance chart show this 15 minute delay for the memory usage?
Note: The CPU usage does not behave this way though. CPU usage comes down immediately after the load test as per the performance chart.
