Creating an index over the database table that is used to store rules is
an important way to improve the performance of rule queries. It is recommended
that an index be created over the rulename column of the table containing
the rules. This greatly improves the performance of rule-triggered queries
that are looking for a rule(s) with a specific name. The index saves teh
query the effort of searching every row in the table. Please refer to the
documentation for your database for instructions on how to create
an index.
