High CPU can result from any of the following factors:
A low value setting for the PollInterval parameter — a low PollInterval value increases CPU usage and the number of I/O operations Replication Extract performs.
A low value for the CIMAX parameter — a low CIMAX value increases the number of I/O operations issued. The effect of the CIMAX parameter is similar to the PollInterval parameter.
A low value for the retry configuration parameter — if the value of the retry configuration parameter is too low, your CPU usage can be unnecessarily high during network outages. This is because the host retries the connection every n seconds, where n is the value specified in the retry configuration parameter. If the value is too high, delays in processing can occur following network outages.
