There is a white paper available from VMware. You can download the complete file here.
On Derek Seaman‘s Blog you can find a few sessions regarding vCenter Performance, e.g.:
Session: INF8108
Teaser: 5.5 to 6.0 is 300% faster for vCenter operations From 6.0 to 6.5(?) is another 100% higher.
HTML5 vs. Flex client: Shows a chart with dramatically faster HtML5 performance over Flash client.
VCSA vs. windows – When you have a datacenter with heavy load the VCSA far out performs Windows vCenter.
A short overview from OpManagers VMware Monitoring:
Troubleshooting
Best-in-class VMware monitoring using over 70 VMware performance monitors
OpManager’s VMware Monitor provides indepth, agentless monitoring of VMware-virtualized servers to give IT administrators a single fault and performance management console for entire server infrastructure – both physical and virtual.
