Context switches much slower in new linux kernels
...mperatures (as compared to idle=poll), less power use and still retain the excellent low latencies of a polling idle loop. Therefore, my updated recommended set of boot parameters for low CPU thread wake up latency based on these findings is:

Accessing class variables from a list comprehension in the class definition

The accepted answer provides excellent information, but there appear to be a few other wrinkles here -- differences between list comprehension and generator expressions. A demo that I played around with:

Why does GCC generate such radically different assembly for nearly the same C code?
..., etc? And then llvm (clang) for different targets?
Mystical has done an excellent job in the thought process required to work through the problem of analyzing/optimizing the code, expecting a compiler to come up with any of that is, well, not expected of any "modern compiler".

It is still generally excellent and highly recommended (by me, and I think by other performance-tuning experts). It would be cool if Ulrich (or anyone else) wrote a 2017 update, but that would be a lot of work (e.g. re-running the benchmarks). S...
