      Description:

      NameLookup performance fixes that address unnecessary updates
      While the Update task is explicitly updating Domino Directory (names.nsf) views, any NameLookup or NIFFindByKey calls that need to access a view being updated will back up on the locked collection until the update is done.

      Any threads waiting on a NameLookup call will wait because the collection is being updated. Thus, you will see this behavior in the form of hangs. For example, NRPC connections (which do a NameLookup for authentication) might either take extra time to complete or return saying 'server is not available'. These fixes may avoid certain Domino hang issues as well.

      Answer
      A number of fixes have been made to improve peformance regarding NameLookup. Two primary fixes were made relative to SPRs CMCY6KBQAR and MLUR6P9TAT to address unnecessary updates stemming from NameLookups. Note that, however, there are still expected cases in which NameLookups will need to update the collection.

      Fixed in Domino releases 6.5.5 Fix Pack 2 (FP2), 6.5.6, 7.0.2, and 8.0. With the exception of Domino 8.0, one must use the following notes.ini parameter to implement the fix:
      Debug_Enable_Update_Fix=8191
      Server_Name_Lookup_No_Update=1
