Content Server uses an in-memory cache to store the object IDs of dumped objects. Before dumping an object, Content Server checks the cache to see if the object has already been dumped.

You can improve the performance of a large dump operation by setting a larger cache size. If you do not specify a cache size, the server uses a default size of 1 MB, which can hold up to 43,690 object IDs.

To increase the cache size, set the cache_size argument of the dump_parameter property to a value between 1 and 100. The value is interpreted as megabytes and defines the maximum cache size. The memory used for the cache is allocated dynamically as the number of dumped objects increases.

Content Server ignores the cache setting when doing a full repository dump.
