Extreme vCenter Performance

vCenter Components:
* Web Client Server
* VPXD – primarily task execution, sends tasks to appropriate host, retrieves config changes, pushes config updates, inserts stats into db, responds to API requests
* SSO – single sign on (talks to Active Directory)
* Database
* Inventory Service (offload queries from VPXD)
* Various other services (eg Health and statistics)
* Content Library

vcenter appliance – vimtop (have to enable ssh)

What affects vcenter:
* ‘churn’ – out of the box settings should be fine for ‘light’ workloads
* Inventory size and host/vm configuration
* #of plugins/extensions
* Stats level and retention settings

Top Consumers:
* Inventory service (java) based on inventory size
* Vpxd (c++)
* ?
* ?

In 6.0 simply add more memory to VM and reboot, and the Heap sizes will be automatically adjusted. (This would not work in 5.5)

Most traffic is write traffic. SSDs provide a significant performance benefit over magnetic storage.
