# TermCachePersistentKB

The amount of memory to allocate to store the most commonly occurring terms.

If you set `TermCachePersistentKB`, the `N` most commonly occurring terms (by total number of occurrences) are stored in memory. `N` is selected so that the amount of memory used to store the terms is as close as possible to the memory allocated in `TermCachePersistentKB`. The default value is `0` (zero), which means that IDOL Server does not cache terms.

Use this parameter only when there is a large amount of available memory, such as in 64-bit applications.

If you set both TermCachePersistentMinOccs and `TermCachePersistentKB`, `TermCachePersistentKB` takes precedence.
