When system option #55 is set, READS with LOCK:Q_NO_LOCK is automatically mapped to READS with LOCK:Q_NO_TLOCK. This setting enables you to make use of the READS prefetch feature of xfServer (and thus improve performance when doing sequential reads) without modifying your code.
Because Q_NO_TLOCK uses fewer resources than Q_NO_LOCK and provides similar performance to a READS on a file opened for input, system option #55 will provide performance gains, regardless of whether or not you use the prefetching feature. |
Do not use this option if you want to see concurrent changes made by other users, as Q_NO_TLOCK does not guarantee changes will be seen. (See LOCK for more information.)
See READS and SCSPREFETCH for more information about the prefetch feature of xfServer.
