You have no idea about computer networking, matrix computing, virtualization or any of that, do you?

Throw more hardware at it, it will get better.

Bull$hit

Installing more servers is not always an easy/quick thing to do, not when you're looking at a complex setup.

@Candina: In most cases you're right, however this is a completely parallelizable operation. Each dungeon could (theoretically) be run on its own physical server without any scaling issues. There is no logical reason they couldn't throw more hardware at this particular problem.

That said, there might be an unnecessary bottleneck or scaling issue somewhere that the server-side updates are working towards removing.

Ahh yes, the old "10 million players x $15/month = $150 million/month" myth...

Hypothetical situation: the top-of-the-line computer you bought a year ago has begun slowing down and becoming sluggish. It takes longer to boot. It takes longer to turn off. Playing WoW is fine once it launches, but that takes longer than it used to.

Solution a: Install another hard drive.
Solution b: Clean the drive and reinstall the operating system.

Which one works best?
