I am running a vSphere 5.5 environment. vCenter Server (VM) is standard with SQL 2012 backend. My vCenter Database is 10GB in size. Transaction logs have ample space allocation and are set to backup and truncate every 4hrs. All default SQL vSphere jobs are running fine. Both vCenter Server and SQL database sit on same subnet and are located on same ESXi host (DRS affinity rule in place).
The problem I am facing is the performance of the Thick client. More often than not (especially when navigating around VM&Templates) the performance is so bad it becomes unusable. When click on a folder or attempting to populate vms, it hangs for 5-10mins. This same issue is not seen in the web client.
Strangely enough, every now and again the thick clients does respond in a more satisfactory manner. I have reset the vCenter Inventory Service database to no avail. VMware support isn't offering much in the way of help or idea. My 10Gb network is still in its infancy of use and the underlying netapp storage is barely 40% utilised and no latency is being observed.
Has any else experienced this issue with the thick client??
