9 of 15 replication tips: Set performance profiles

For optimal SQL Server replication performance, you should set your HistoryVerboseLevel to 0 for your Distribution Agents. Ideally you will create a high performance profile for this -- performance will increase 10-25% per command! Doing so will not yield any Error Details when your Agent fails, so you will need to select the default profile and restart your Distribution Agent to view the error in Error Details. Do not set HistoryVerboseLevel to 0 on your Log Reader agent; this will cause very high CPU utilization.
