Performance deteriorates if VMs have snapshots

If VirtuCache cache media latency is low and VirtuCache write replication latency is also low, but you see high VM write latency, then please make sure that there are no snapshots on the VM. The below screenshot is an example of this problem.

If the read latency is high and/or  the cache hit ratio is low, that too might result from a snapshot on the VM, as shown in the below read latency chart.
