... performance is alignment

woah -- Buzzword alert! "Alignment" what does it mean, and why is it relevant to performance?

Let me explain this by reference: when you go to the local PC superstore to buy a piece of software, on the back of the box will be a "minimum requirements specification" looking a bit like this:
  • 2 GHz processor
  • 1 Gb RAM
  • VGA graphics adapter
  • ...

But when you buy enterprise class software, there's no spec like this on the box! That's because performance of the software is directly related to the workload it's servicing: how many users, how much concurrency, how many transactions...

Performance alignment means that whatever resources you allocate to a task should be proportional to the workload it is processing. This kind of alignment means your investment is proportional to the business demand: right-sized for the job in hand.
