3.23. Status Cache Limits

The Status Cache (AFS Configuration Control Panel: Advanced Page) is defined to have a maximum number of entries. Each entry represents a single file or directory entry accessed within the AFS file system. When the maximum number of entries are allocated, entries will begin to be reused according to a least recently used (LRU) algorithm. If the number of files or directories being accessed repeatedly by your applications is greater then the maximum number of entries, your host will begin to experience thrashing of the Status Cache and all requests will result in network operations.

If you are experiencing poor performance try increasing the maximum number of Status Cache entries. Each entry requires approximately 1.2K. The default number of Status Cache entries is 10,000. This can be adjusted using the Stats registry value.
