| == LOTUS TRAVELER THREAD POOLS ==
| | Page moved to [[Lotus Traveler: Tuning English]] |
| | |
| Lotus Notes Traveler has four thread pools that can be tuned:
| |
| | |
| * '''Prime sync threads''' - Determine if changes to user mail files need to be synchronized to user devices.
| |
| * '''Device sync thread'''s - Synchronize data between Domino mail servers and user devices.
| |
| * '''Worker threads''' - Used internally in the device synchronization process.
| |
| * '''HTTP threads''' - Used by the HTTP task, one per HTTP connection.

| |
| | |
| | |
| The following are general guidelines for the relationships between the number of threads in each of the thread pools.
| |
| | |
| * Prime sync threads should be much less than the number of device sync threads; normally the prime sync default of 10 threads should be adequate.
| |
| * Worker threads should be double the number of device sync threads.
| |
| * HTTP threads should be 1.2 times either the number of device sync threads or the number of ActiveSync devices, whichever is larger.

| '''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.

| === 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 the'''Hitrate''' is near 100%, and'''DisplaceRate''' is 0%. Increasing the value of the field'''Maximum cached designs''' improves response-time.
