Analyzing Replication Divergence Data

Try to determine if the replication divergence is a result of low disk performance on the consumer using the output of the iostat tool. For more information about diagnosing disk performance problems, see Example: Troubleshooting a Replication Problem Using RUVs and CSNs.

Replication divergence is typically the result of one of the following:

• The network's capacity is not large enough to guarantee transport speed at the rate that updates are generated. The network capacity may the problem when operating over a very low bandwidth.

• Consumer not fast enough to apply the changes is receives. For example, consumer speed can be an issue when disk usage is saturated or when a problem occurs when replication is happening in parallel (unindexed searches, for example).
