What's the point of Symlink'ing folders? If your hard drive is reading from the exact same location for data being accessed for all five (or whatever) clients, then how does it help performance?
With a symbolic link the OS knows that the 5 copies of the same gignormous data file that are simultaneously being loaded by wow.exe really are the same file, so it only loads them once. If you just copy and paste the wow folder it thinks they are different files and you get disk thrashing.
