I have an esxi host with about 132 GB of RAM. It is showing between 88% and 92% memory usage. I only have 3 servers running on this host. A vCenter 5.5 appliance, a DC, and exchange 2013. On exchange vm summary, consumed host memory is 112942.00 MB. Active guest memory is 10485.00 MB. Task manager on exchange shows only 45% memory usage. Nonetheless, exchange is running slow.
Any ideas on how to deal with this are greatly appreciated.
