vCenter 6 Wait Chain Stats

On my Windows 2012 R2 server which has 8 vCPU's and 28GB of memory, I have noticed the java and vpxd process are showing threads in wait when I look at the wait chain stats under performance monitor. I stated to look into performance on my vCenter server to understand why data in vCenter i.e: host stats or anything else does not always seem to update in a timely fashion. I have opened a case with Vmware and they could not see anything wrong in the logs but any search online leans towards the fact that any type of wait chain is bad. Also I have to disable my AV program and it had no affect.

Any thoughts from the Experts out there?

How do you measure wait chain?
Why are you using so much RAM? vcenter hardly ever exceeds 4GB

Sorry for the delay we have very large environment and java does take are large amount of resource also the sizes guide from VMware states out environment needs these resources. I am not measure Wait Chain but asking or trying to understand why I am even seen any process in a wait state

Can you make a screnshot of CPU RAM and Disk performance graphs of vcenter VM?

The attached Word document  lists the CPU and disk usage on the vCenter VM along with a screen shots of the wait chain processes I am referring to.

Thanks Again.....

Please take all measurements from outside virtual machine.
e.g. on a completely overcommitted host all VMs will get 5GHz CPU via CPUID, just that what they get is 10x slower than real stuff.

The attached file contains screen shots from our Vmware environment monitoring application and listed stats for the vCenter server and DB.

I understand but I thought I could grab stats from a 3rd party outside of vcenter since vcenter is the one that I am questions the performance on

I wanted to thank everyone for their help with this. Since VMware support could not find any issues and I had our network team and db teams review this as well with no issus found I will close this question but still explorer why I am seeing Wait chain when I have more time
