WebbAfter the leap second was inserted, applications calling system calls that used futexes consumed almost 100% of available CPU time. This occurred because the kernel's timekeeping structure update did not properly update these futexes. The futexes repeatedly expired, re-armed, and then expired immediately again.

Webbindirect overhead of periodic OS clock interrupts (“ticks”), that are used by all general-purpose OSs as a means of main-taining control. This is shown for various grain sizes, plat-forms, tick frequencies, and OSs. To eliminate such noise, we suggest replacing ticks with an alternative mechanism we call “smart timers”. http://blog.chinaunix.net/uid-26299634-id-4197141.html
