I have some clients using Merge Replication. They may not replicate for a few days at a time which could result in thousands of Updates & Inserts been needed. This could be any thing from 100,000 to 500,000 records.Needless to say this can take a long time , and more often than not will fail. Is there anything I can do to help the situation and improve performance ? Is it worth looking at Web Synchronization - would this be quicker or slower ? Ant thoughts would be appreciated.
