Scripts to generate a load under a Windows or Linux VM

1.0 Overview

These could be used for stress testing your ESX Servers  One is VBscript for Windows VM's and the other is Perl for *nix (Unix/Linux) VM's.  Once you've started the .vbs one you can stop it by killing the wscript process under Windows Task Manager.
