I found much of the reason for it starting slowly, was the USB port that the drive was plugged into. The two side ports are different, according to the device manager. I have two side and four rear USB ports.
1) Standard Enhanced PCI to USB Host Controller (side ports).
2) Standard OpenHCD USB Host Controller (rear ports).
After discovering this, I plugged the drive containing Mint 9 into one of the side ports, what a difference it made! I now have 7 Home Premium running in Oracle's Virtual Box inside of Mint, it runs faster than Mint itself ran in the back ports.
Plus, one other thing to consider, this was the original hard drive that came with the computer last November. It's mounted in a case with it's own power supply, and it's still a perfectly good drive (320GB SATA, 7200 RPM). But a USB port is not the native connection for this drive, so performance will drop some. However, this same drive, plugged into my laptop, runs circles around the installed drive within it.
So finally, I do have decent performance out of Mint 9, and now am a happy camper.
