3.5. Tuning or Upgrading
Once the bottleneck is identified, there are two choices. Either the amount of the resource can be increased, or the demand for the resource can be reduced. Tuning techniques will be discussed along with the particular bottlenecks. However, there are some general tips that can be applied to tuning bottlenecks:
Determine whether the data indicate a particular bottleneck.
Devise a simple test for measuring results.
Do not tune randomly.
Use heuristics and logic in choosing what to tune.
Look for simple causes.
Develop an action plan.
Change only one thing at a time.
Prioritize the goals.
Know when to stop tuning.
