Virtual PC and download speeds

[Theslaz]

Playing around with Microsoft's "Virtual PC" this past weekend.
Successfully got it installed and working properly ( I think! ). Did
some experimenting with downloads using the P2P network. Specifically
downloading movie files. Have been downloading files using my desktop
and a laptop that I have right beside for quite some time now. The best
transmission rates that I could get out of both machines would average
some where around 50 Kps.

Tried downloading through the "Virtual PC"; in which I have installed
Windows XP pro. The same operating system as the desktop and the laptop.
(Virtual Pc is installed on the Desktop ). I had all three computers
download the same movie file using the same Torrent file. The Desktop
and the laptop did their usual download at about 55 Kps; the "Virtual
PC"; would you believe was at a high of 150 Kps.

I then tried one other file that I was downloading on the laptop and it
was stuck on being connected to two peers and downloading at 7 Kps. The
"Virtual PC" connected to 12 peers and hit a high of 84 Kps.



One other twist I have added. I decided to try a different Virtual PC.
Downloaded "VMware Player"; installed it and loaded a Virtual file that
has Windows 7 on it. Getting 155 Kps as I speak downloading a movie.

My question is "Why" the better performance within the virtual Machine??

DId you by any chance start the download of the torrent in your VM AFTER
you started it in your normal PC?
If so, chances are that your Virtual PC was getting a great connection
to ...... your normal PC.

If you want to do a more reliable test, don't use Torrents, use a real
download somewhere.
