I set up a virtual machine with freebsd 9.3 (I also run relayd), and when I execute command top, I get the following results which is kind of wierd:

Does anybody know why CPU information shows empty percentage?
Any help would be appreciated!
When you initially open top, it should be empty. It fills it in on 1 second intervals by default. You should be able to hit spacebar and refresh it. You can try the -q flag to speed up top's priority to get it to refresh more frequently. Since it's running in a virtual machine, the system clock may be off and it's having trouble polling.
If your virtualization software has any add-ons for FreeBSD, you should consider installing them for a smoother experience. e.g. vmware tools
