RDI Cache Size

Project-level NCrunch configuration setting Introduced NCrunch v5.0 Default Value: 10,000
ID/Tag in config file: RdiCacheSize


This setting controls the size of the internal cache used by RDI during collection of data at test run time.

This cache (sized by number of entries) is used by RDI to reduce data redundancy in log files. It significantly improves data collection performance and reduces disk space consumption.

The value of this setting will be applied to all tests in its associated project. As such, this setting is only useful for test projects and will have no effect on projects containing no tests.


The setting provides a balance between performance and memory consumption in the test execution process. A larger cache requires more memory but will improve overall efficiency when dealing with large tests that process many disparate data elements.
