Cache User Info

To optimize the response time keeps Domino design elements in memory.

Tune	To change the parameters of Web Cache, Open the server document and go Internet Protocols → Domino Web Engine → Memory Caches. and change the field value Field Description Maximum cached users Enter the number of users to cache. The default is 64. After a user successfully authenticates with a server, Domino stores in memory the user's name, password, and the list of groups to which the user belongs. Use this field to increase the number of users for whom Domino stores this information.
Statistics	Domino.Cache.User Cache.Count Domino.Cache.User Cache.DisplaceRate Domino.Cache.User Cache.HitRate Domino.Cache.User Cache.MaxSize
Interpretation	Good = HitRate >= 97% Good = DisplaceRate = 0

Example

To find out if you need to change this parameter, run the following command

 > Show stat domino.cache.user*
Domino.Cache.User Cache.Count = 68
Domino.Cache.User Cache.DisplaceRate = 0
Domino.Cache.User Cache.HitRate = 73.258795221749
Domino.Cache.User Cache.MaxSize = 64

Observing these numbers we can deduce that the value of elements (Count) has reached the maximum (MaxSize), so elements in this cache are discarded ( DisplaceRate).

The optimal value for theHitrate is near 100%, andDisplaceRate is 0%. Increasing the value of the fieldMaximum cached designs improves response-time.
