comment Windows 7 kills VMWare performance by disk caching?
The mainMem.useNamedFile="FALSE" is key. Without this entry vmware will allocate a file on the host disk to hold the entire contents of the guest RAM and can continuously thrash the host's disk with the guest's RAM in some cases. In the worst case I've seen the guests be completely unusable. In the best case the guests still end up being significantly slower most of the time. I've yet to see a case where leaving this parameter enabled has actually helped performance except that it makes suspends faster.
