Article: Domino Name Lookup Cache »

Look at your Notes.ini file on the Domino Server.
If you see this parammeter:
NLCACHE_SIZE=33554432 og NLCACHE_SIZE=67108864
Some one in your organization has payed attention to the IBM Business Partner
It means that the amount of memory used for Name look up has been set to 32 MB or 64 MB.
How do you check to see if this is the right size and performance the best ?
Go to your Domino console and write: Show Stat database.namelookup*
You will get something like this:
show stat Database.namelookup*
Database.NAMELookupCacheCacheSize = 131.012
Database.NAMELookupCacheHashSize = 1.379.435
Database.NAMELookupCacheHits = 240.613
Database.NAMELookupCacheLookups = 387.402
Database.NAMELookupCacheMaxSize = 67.108.864
Database.NAMELookupCacheMisses = 112.160
Database.NAMELookupCacheMisses.ItemMisses = 111.816
Database.NAMELookupCacheNoHitHits = 34.629
Database.NAMELookupCachePool.Peak = 2.097.152
Database.NAMELookupCachePool.Used = 1.657.120
Database.NAMELookupCacheResets = 0
Database.NAMELookupCache.ContainerResets = 1
Database.NAMELookupCache.CriticalContainerResets = 0
Database.NAMELookupCache.EligibleContainerResets = 2
Database.NAMELookupMisses = 230
Database.NAMELookupTotal = 371250
Database.NAMELookupTotalLookupTime = 88,263
