A Windows virtual machine (VM) is experiencing poor application performance. The suspected issue is a lack of available memory. Windows Task Manager shows 30% of the memory within the VM is not currently being used. What does this indicate and what could be checked next?
The VM has memory available, however it may not actually have physical memory available.
VMkernel swap activity on the ESX Server host should be checked next.
Windows Task Manager is not reading actual memory usage in the VM. Windows System Monitor should be used to get a precise reading on memory usage.
The application problems are definitely due to a non-memory related problem. CPU affinity settings should be checked for this VM.
The application problems are definitely due to a non-memory related problem. CPU utilization should be checked next using Windows Task Manager.
The poor application performance due to suspected lack of available memory suggests paging is the cause of the issue. If Windows Task Manager shows 30% of the memory within the VM is not currently being used, then paging must be occurring within the VM host. Therefore poor application performance should now be checked.
