Well, the AMD device is 100 Mbs, while the Intel device is 1000
Mbs, so you can't compare them. Since NICs work at a limited
speed (very much slower than any modern disk drive, even at 1000
Mbs), I don't know why you are seeing those numbers. My guess is
that you do not have a good setup. You also need to remember to
mark virtual disk drives as being SSD, in the VM, or VBox will
insert seek delays. It doesn't matter what the real disk is.

There is a way, but I don't remember how. I am sure it is in the docs
somewhere.

From the little that I know about ESX, it does not virtualize a
machine. It shares a real machine with more than one operating
system. If it works, use it.
I still think you have a bad setup in VBox, but I don't have the time
to try to figure it out. There was a post, some time ago, in this mail
list, about how to make a modern VBox setup for OS/2 (probably
eCS at the time). If you can find that, it will probably help.
