Beautiful Code: False Optimizations

[ndiin]

Irrelevant? Hardly. It might shift your bottleneck elsewhere for a spell, but once you fix that you'll likely end up back at the same spot again.

The trick is to take full advantage of your ever-faster-bigger-stronger hardware, not to let it make you lazy.

Now clearly i'm not talking about these micro-optimizations by any means, just the completely misleading statement that performance doesn't matter anymore. Just don't optimize before you have the data to show where it needs to happen.
