[asterisk-biz] ASTERISK running under VMWARE

[David Shauger]

I ran some tests on an quad core server with 8GB of memory running Xen  
on OpenSUSE and it was really terrible. However, VMware Fusion on a  
Mac mini Core Duo with 2GB works rather well. Conferencing three  
people we sometimes lose audio for one of the three so it has its  
limitations. Parallels Desktop was not up to the processing task at  
least version 3.
