+ Set scheduler wake cleanup threshold. Default is medium. + This flag controls how eager schedulers should be requesting + wake up due to certain cleanup operations. When a lazy setting + is used, more outstanding cleanup operations can be left undone + while a scheduler is idling. When an eager setting is used, + schedulers will more frequently be woken, potentially increasing + CPU-utilization. +

+
Erts 5.10.1.1 + +

+

+ Own Id: OTP-10926

+
+ +

Fix a problem in erlang:delete_element/2 where + the call could corrupt one word of stack if the heap and + stack met during call.

+

+ Own Id: OTP-10932

+
+ +

+ The +sws<value> and + +swt<value> + system flags failed if no white space were passed between + the parameter and value parts of the flags. Upon failure, + the runtime system refused to start.

+

+ Own Id: OTP-11000

+
+
+
+ + +
Improvements and New Features + + +

+ Scheduler threads will now by default be less eager + requesting wakeup due to certain cleanup operations. This + can also be controlled using the +swct command line + argument of erl(1).
