There is a VMware setting which you can set which should give you a small but noticeable performance improvement in SQL Server performance when that SQL Server is running within a VMware Virtual Machine.
This setting is the Large Pages setting. This will allow the SQL Server to allocate memory from the host in 2 Meg chunks instead of 4k chunks. This has been shown to provide up to a 6% performance improvement in performance, however your mileage may very.
This setting can be found by editing the Hosts Advanced Settings on the Configuration tab. The setting is Mem.AllocGuestLargePage.
