Cache Expiration & Eviction

This section contains configuration settings for optimizing Cache Eviction and Expiration. It defines parameters such as the bulk removal size and the delay interval between consecutive removal operations, which help maintain cache performance during cleanup activities.

Note

This feature is also available in the NCache Community Edition, except for Default Expirations, Least Frequently Used (LFU), and Least Recently Used (LRU) eviction policies.

Cache Expiration

Expired items are removed in bulk. The ExpirationBulkRemoveSize specifies the size of the bulk operation, i.e., how many items should be removed in one bulk operation.

<add key="NCacheServer.ExpirationBulkRemoveSize" value="10" />

As expired items are removed in bulk, this may affect the performance of user operations during Expiration. The ExpirationBulkRemoveDelay (specified in milliseconds) results in a delay between two consecutive bulk remove operations.

<add key="NCacheServer.ExpirationBulkRemoveDelay" value="0" />

Cache Eviction

During Eviction, items are removed in bulk. The EvictionBulkRemoveSize specifies the size of the bulk operation, i.e., how many items should be removed in one bulk operation. The EvictionBulkRemoveSize has the default value of 10.

<add key="NCacheServer.EvictionBulkRemoveSize" value="10" />

As items are removed in bulk during Eviction, this may affect the performance of user operations during Eviction. The EvictionBulkRemoveDelay (specified in seconds) causes a delay between two consecutive bulk remove operations.

<add key="NCacheServer.EvictionBulkRemoveDelay" value="0" />
