Hi all,<div>I&#39;ve noticed libdispatch will poll event sources with an one-entry kevent receiving queue(queue_kevent.c:162, in function &quot; _dispatch_mgr_invoke&quot;). This will incurs more system calls and hence poorer performance. Why not poll event sources with a larger kevent receiving queue?</div>
