Hi,

Some of the reasons:

1. The speed of computing might be wasting valuable human time (users waiting for response);

2. Enable your system to keep-up with the speed business is conducted; and

3. Optimize hardware usage to save money (companies are spending millions on hardware).

For more info, see chapter 1 (Performance Tuning Overview) of the Oracle Database Performance Tuning Guide.

Best regards.

Frank

Performance Tuning is as important as High Availability of the system for some businesses. For example, for a brokerage or internet business' like Fidelity, Amazon.com or eBay.com, inability to do service user requests results in lost revenue. Not having a performant system for a few days during holiday season, would mean serious trouble. For this reason, not only they need to pay attention to HA but also, for SLAs during peak processing time.

Performance Tuning is also important, since throwing more CPU and memory doesn't solve underlying problems (for e.g., bad applicaiton design, or SQL). Getting to the root cause is important in these cases...

...even worse, this could make your application go even slower !
