If you're going to run FreeSWITCH inside a virtualized Windows Instance, you may as well go with Microsoft's Hyper-V. Windows Server seems to work better under Hyper-V than Xen or OpenVZ. You could try assigning the VM a higher CPU weight, (not sure how VMware handles that) to see if that solves the issue.

Xen seems to work well, openvz is recommended by the devs. Other than that make sure your resources are allocated properly. Thank you, Brian Foster Project Manager/Owner's Rep.
