The optimizer uses ratio values to focus on the upper percentage of the most relevant values and tests.
When dealing with a large number of rules at one time, the optimizer must analyze a huge number of values and tests that come with the rules.
Only the most relevant values and tests are chosen. You can also tell the optimizer to focus on the upper percentage of the most relevant values and tests by applying optimization ratio values.
An optimization ratio is a floating-point value between 0 and 1.
0 means that no value or test among the most relevant ones is optimized.
1 means that all the values or tests among the most relevant ones are optimized. This is the default value.
Value and test optimization ratios are two independent capabilities. You can activate them separately for the sequential execution mode. To do so, you can use IRL properties, Java API, or Java properties.
