Prefetch Priority (-prefetchPriority)

Use Prefetch Priority (-prefetchPriority) to utilize a "pollskip" that adds the specified number of records to the network message of an in-process prefetch query without additional polling.

n

The number of prefetch records to add to a network message.

Adding more than one record to the message at a time can greatly reduce the number of poll() calls being made on a large database configuration. The expected result is that reducing poll() calls improves overall system performance by decreasing the "System CPU" cycles, allowing for increased "User CPU" cycles. The pollskip only occurs if the previous poll() call returned nothing waiting.
