I have VMware Workstation 7.1.5 build 491717 running on an HP Pavilion dv7-4110em XE287EA#BED with an Intel Core i7-720QM CPU with 4 cores and 8 logical CPUs and Windows 7 Ultimate 64-bit Service Pack 1. The CPU works with 4 cores up to 1.6 GHz. In automatic Intel Turbo Boost mode, it works with 2 cores up to 2.4 GHz, and one core up to 2.8 GHz. I have never seen it work above 2.4 GHz. What is the optimal number of processors and cores to configure VMware virtual machines with, running the following operating systems:Windows XP Professional 64-bit Service Pack 2Windows XP Professional 32-bit Service Pack 3Windows 7 Ultimate 64-bit Service Pack 1OpenSUSE 11.3 64-bitMy current configuration with 1 processor with 4 cores is slow relative to the speed of the operating system on the physical machine.
