For example, + "+SP 50:25" sets the number of scheduler threads to 50% + of the logical processors configured, and the number of + scheduler threads online to 25% of the logical processors + available. The +SP option also interacts with any + settings specified with the +S option, such that the + combination of options "+S 4:4 +SP 50:50" (in either + order) results in 2 scheduler threads and 2 scheduler + threads online.</p> + <p> + Thanks to Steve Vinoski</p> + <p> + Own Id: OTP-11282</p> + </item> + <item> + <p> + Extend erl_driver interface with lock names</p> + <p> + Lock and thread names are already a feature in the driver + interface.
