Sounds to me like a harddisk problem,
Well... not so much a problem, but you cannot run that many WoW instances off the same harddisk without expecting a ton of lag.
Actually I run all 5 instances of wow off of a single sata hdd.
Two physical installs, 1 for main and the other for the alts(run 4 times from the same dir

I have no problems with lag.
