A history of extreme slowness in virtualization with AMD 9600 x4 Quad Core?

Depends on what you are running as a guest

I am running a VM with Windows 7, running a Delphi Xe2, is very slow, usaroutro the hardware I use normally.

What is the bit count of the host and the guest?

64 bits in the host and guest, CPU usage is always 100%

What is the host?
Post the guests log file (as an attachment)
As well as from the hosts terminal/command window type VBoxManage showvminfo <VM Name> --details and post here. Replace <VM Name> with the actual name of the VM. Use " " if the name has a space in it.

Note if the host is Windows you need to be in the directory that has VBoxManage.exe for the command to work.

I could explain better how to send and where to make this command ...

Its a generic script meant for various guests, but you go ahead and criticise.
