# Entry Cache

*This is an abstract object type that cannot be instantiated.*

Entry Caches are responsible for caching entries which are likely to be accessed by client applications in order to improve PingDS directory server performance.

## Entry Caches

The following Entry Caches are available:

* [FIFO Entry Cache](objects-fifo-entry-cache.html)

* [Soft Reference Entry Cache](objects-soft-reference-entry-cache.html)

These Entry Caches inherit the properties described below.

## Entry Cache properties

You can use configuration expressions to set property values at startup time. For details, see [Property value substitution](expressions.html).

| Basic Properties                                                          |
| ------------------------------------------------------------------------- |
| [cache-level](#cache-level) [enabled](#enabled) [java-class](#java-class) |

### Basic properties

Use the `--advanced` option to access advanced properties.
