BTW, could we define some concrete metrics to asses all the ongoing changes performance-wise? We have the timerbench, we have cyclictest (for large number of timers and for POSIX tests), we have the enhanced runtime statistics for threads and IRQs, now we just need to create meaningful test scenarios and run them / let them run on the different platforms. Interesting is, e.g., how the timer subsystem scales worst case-wise and what piece of the cake remains for Linux under high timer load. Moreover, there is still that tsc2ns conversion improvement to work out - and then to evaluate...
