The following guidelines can help you configure parallel DSI to achieve optimal performance. The objective is to tune parallel DSI processing to provide the best replication performance, balancing parallel processing with acceptable levels of contention. Contentions will always occur. The only way to eliminate contentions is to turn off parallel DSI processing. At the same time, setting all parallel DSI parameters for maximum parallelism may cause Replication Server to spend more time recovering from contentions than actually applying transactions to the replicate. Optimal performance is achieved through a clear understanding of your operating environment so that you can successfully balance parallel processing with acceptable contention levels.
