This section discusses tips on how to improve the performance of using R-tree indexes. It includes topics on how to maintain accurate statistics and how to improve the performance of queries that use R-tree indexes.
You might also want to refer to Designing a User-Defined Data Type, which describes performance considerations when designing the user-defined data type of the column that is indexed with an R-tree index.
For other performance issues that are also relevant to R-tree indexes, refer to the IBM Informix: Performance Guide.
