+ disabled at compile time (<c>--disable-threads</c> had
+ been passed to <c>configure</c>), and the <c>+A</c>
+ command line argument of <c>erl</c> was passed when
+ starting the runtime system, <seealso
+ marker="erl_driver#driver_system_info">driver_system_info()</seealso>
+ erroneously claimed that the runtime system had async
+ threads even though it had not.</p>
+ <p>
+ Due to this bug the file driver did not split tasks into
+ smaller chunks, but instead completed the whole task at
+ once, i.e., the scheduler got occupied with I/O for a
+ longer time than intended.</p>

+ A proposal for a new scheduler wakeup strategy has been

+ A switch for configuration of busy wait length for
+ scheduler threads has been added. For more information

+ </item>
+ <item>
+ <p>
+ The extra memory barriers introduced by bug-fix OTP-9281
+ were unnecessarily used also on tables without the
+ <c>write_concurrency</c> option enabled. This could
+ unnecessarily degrade performance of ETS tables without
+ <c>write_concurrency</c> on some hardware (e.g. PowerPC)
+ while not effecting performance at all on other hardware
+ (e.g. x86/x86_64).</p>
+ <p>
+ OTP-9281 (R14B03): ETS tables using the
+ <c>write_concurrency</c> option could potentially get
+ into an internally inconsistent state.</p>
