How to optimize vCSA Tiny peformance housed over 100 VMS? [closed]

I would recommend to disable also VMware Performance Charts and VMware Content Library Service. Check the list in the source to disable more unused service in your configuration.

Yes, it will work.

Notes:
Tiny Environment (up to 10 Hosts, 100 Virtual Machines)
Small Environment (up to 100 Hosts, 1,000 Virtual Machines)
Medium Environment (up to 400 Hosts, 4,000 Virtual Machines)
Large Environment (up to 1,000 Hosts, 10,000 Virtual Machines)

If you find that you need more resources for your vCSA, add RAM or CPU to it. I don't think your environment will simply fall over if you cross the 100 VM threshold.

Am I missing something?

One other option might be to backup your tiny VCSA and restore it to a newly-deployed small VCSA.
