As per reference architecture from vCenter 5.5 Deployment Guide Whitepaper http://www.vmware.com/files/pdf/vcenter/VMware-vCenter-Server-5.5-Technical-Whitepaper.pdf

The recommended approach in almost all scenarios involves a single VM for vCenter & separate VM for Database.

All vCenter components (SSO, Web Client, Inventory, vCenter) in 1 VM.

The recommendation (soft recommendation) to centralize SSO+Web Client is when you have 8+ vCenter Servers.

Regarding Web Client performance, you can increase the JVM Heap Size for Web Client as the default is 1GB.

Hi,

how big is your environment? How many Hosts/VMs?

In small to mid sized installations, I don't see any problems with the web client installed on the vCenter Server.

Do you use the Windows version of vCenter?

What's the CPU/RAM assigned to the VM?

Regards

Tim
