Increase VM performance
We are using ESXi 5.1. I have to increase performance of a VM by increasing number of CPU. I've to increase total 8 numbers of CPUs but I am confused about which option should I choose so that the VM performance will increase-
Shall I go for-
Number of virtual sockets : 2
Number of cores per sockets : 4
or shall I go for-
Number of virtual sockets : 4
Number of cores per sockets : 2
Shall I go for-
Number of virtual sockets : 2
Number of cores per sockets : 4
or shall I go for-
Number of virtual sockets : 4

It absolutely depends on the kind of application..
Very often increasing CPU's won't help at all in improving performance. It can rather be the contrary. More RAM is usually more effective, or also using a better disk setup.

The sever has enough RAM but it's CPU utilisation spike is very high. That's why we are increasing CPUs. Considering only MS Office 2013 application running on the system what CPU configuration I should opt for?
you may be over subscribing your CPUs to other VMs as well, this will cause the vms to have to wait for cpu time, waiting for 8 CPUs may take longer than waiting for 4 or 2. You need to look at your stats before throwing more CPUs at it.
