Description
Determines the maximum number of entries that can be stored in the user account information cache. This cache stores information about users who recently sent messages to the computer.
When Message Queuing receives a message, it uses user account information to verify that the sending user has permission to send messages to the particular queue. Storing user account information in the cache reduces the time it takes to verify user permissions.
I the cache is full (that is, the number of entries is equal to the value of UserCacheSize ) when the next entry arrives, Message Queuing deletes half of the entries in the cache. The oldest entries are deleted first.
