Aside from making sure the vms have updated tools and hardware...
Are there any other settings that would eliminate CPU\memory overhead.
I know realtime scanning might be an issue...
Any exclusions? for both server\desktop?
Any TCP/IP tweaking when running ESXi 5.5 within the virtual machines
Screen savers, power options..
I seen some people indicate to disabletaskoffload, enable tcpchimney and enable TCPA and Enable RSS
While others disable... any performance gain one way or another
Any other tweaks? alot of VMS and its causing overhead and pegging, so we need to tweak something, without adding host at this time.
So feel free to list all the tweaks done to a virtual machine (server/desktop) alike.
All operating systems is some flavor of windows.
Desktop = Windows 7
