When you know your code is destined to fail, you want it to fail faster. We looked at the statistics and ratios and kept coming up with theories, the trouble was that none of them were right. It was a really long day. The word wait invites a mental model that actually obscures your thinking about performance.

You can determine exactly where a system’s performance problem is, and with equal importance, where it is not, in just a few minutes–even if the problem is several years old.

Optimizing Oracle Performance cuts a path through the complexity of current tuning methods, and streamlines an approach that focuses on optimization techniques that any DBA can use quickly and successfully to make noticeable–even dramatic–improvements.

One is not inherently better or worse than the other. And an expensive hardware upgrade may not help either. Second, understand that the excellent ideas people use to optimize other software are excellent ideas for optimizing Oracle, too: Oracle DBAs and developers are all too familiar with the outlay of time and resources, blown budgets, missed deadlines, and marginally effective performance fiddling that is commonplace with traditional methods of Oracle performance tuning.

If I could fail faster, I could performane my problem earlier, get more work done, and ship my improvements sooner.

It is destined to fail on that test case. Why would you want a business idea to fail fast?
