I've been a long time customer with VMWare. Starting in 1997 using it under Linux. However, the performance problems under Mavericks don't seem to be taken seriously. It is NOT Mavericks because Parallels does not seem to have a problem with this. I've had several support tickets about the problems I am having; such as sluggish performance, extra mouse clicks and the guest OS freezing after left idle for a period of time. Every support person focuses on the mouse problem and ignores the others. I don't have time to talk to you guys over and over again about mouse problems that you don't fix anyway!
I'm sorry, but the only choices you guys leave me is wait for an update and hope that it fixes the problems or move to Parallels. I've been using Parallels without any of these problems.
I wish I could get a refund for the upgrade.
