The percent of a message buffer to fill before sending it to a waiting remote client.
Use Prefetch Factor (-prefetchFactor) to establish a percentage of a network message required to contain prefetched data before sending the message to a waiting remote client.
The number of records in a network buffer is also influenced by PrefetchNum Recs (-prefetchNumRecs) parameter. See Prefetch tuning for a discussion of the interaction between the parameters.
