Sync Framework SLOW using WCF Service? RRS feed

  • Question

  • We've implemented Sync Framework for a client.  WPF applications uisng SQLCE LocalDataCache, WCF Sync Service, SQL 2008 R2 central database.  When connected directly to the database, sync happens quickly.  When using a WCF Sync Service the sync trace shows that the delay is happening here: 

    INFO   , MYAPPLICATION.vshost, 15, 03/21/2012 17:10:52:554, --- End Client Enumerating Changes to Server for Group "LocalDataCacheGlobalSyncGroup" ---
    INFO   , MYAPPLICATION.vshost, 15, 03/21/2012 17:15:11:677, ----- Client Applying Changes from Server for Group "LocalDataCacheGlobalSyncGroup" -----

    I'm not sure what's going on between these two steps in the process.  All prior and post Sync Stages happen in a matter of < 3 seconds.  The sync does complete, just takes so long it is unacceptable for the clients needs as they will need to sync 10 - 20 times the data which takes > 30 minutes.

    I appreciate any suggestions and direction.  Thank you much!
