Lotus Domino: Tunning English

This wiki will be creating a series of articles outlining best practices for Lotus Domino environment.

I ask you to always return to this article will be updating as usual.

Disabling the Collection of Statistics Platform

Domino statistics collection platform to display the Administrator. The collection does not consume much resources, but we're talking about tuning.

To disable the collection utize the following parameter in NOTES.INI.

Platform_Statistics_Disabled = 1

Reasons:

You do not want to collect statistics
On partitioned servers (DPAR), each server collects the same statistics. You can enable only in one partition and disable the others.

Cache Design Elements

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

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 designs	Enter the number of database design elements to cache for users. The default is 128. When a user opens a database, Domino maps each design element name to an identification number. This mapping procedure takes time. Use this field to Specify how many elements you want to store in memory so the next time the user accesses That element, it is Immediately available.

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

 > Show stat domino.cache.design .*
 Domino.Cache.Design.Count = 128
 Domino.Cache.Design.DisplaceRate = 18.0328294698918
 Domino.Cache.Design.HitRate = 81.960226776015
 Domino.Cache.Design.MaxSize = 128

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.
