 If this option is enabled, |XtraDB| uses the ``SYS_STATS`` system table to store statistics of table indexes. Also, when |InnoDB| opens a table for the first time, it loads the statistics from ``SYS_STATS`` instead of sampling index pages. If you use a high ``stats_sample_pages`` value, the first open of a table is expensive. In such a case, this option will help. Note: This option may cause less frequent updating of statistics. So, you should intentionally use the ``ANALYZE TABLE`` command more often.

 Bug Fixes
 =========
 
-  * Fixed |InnoDB| I/O code so that the interrupted system calls are restarted if they are interrupted by a signal. |InnoDB| I/O code was not fully conforming to the standard on POSIX systems, causing a crash with an assertion failure when receiving a signal on ``pwrite()``. Bug Fixed: LP :bug:`764395` / |MySQL| bug `#60788 <http://bugs.mysql.com/bug.php?id=60788>`_ (*A. Kopytov*)
-
-  * The maximum value for ``innodb_use_purge_threads`` has been corrected to 32 (maximum number of parallel threads in a parallelized operation). The :ref:`innodb_purge_thread` patch accepted a value up to 64 for the ``innodb_use_purge_thread`` variable, leading to an assertion failure for greater than the actual maximum. Bug Fixed: :bug:`755017` (*L. Biveinis*)
