finally some patches on no_hz, anyone using it besides me?

I found my system was slower when using it, though I think it uses less power which might be good if you're running on battery

I wonder how much impact these patches have on the "a decade of wasted cores" problems... https://www.phoronix.com/scan.php?pa...-Scheduler-Bad

I wouldn't say it's "a decade of wasted cores" since there's nothing better than Linux in this area. Oh, and their conclusions are crap:

Something like Tannenbaum bullshit.

Yeah I'm sure that the vast majority if not all computers on the top500 list runs linux because of its terrible handling of multiple cores

its terrible for gaming and desktops.

I would not exactly say that Tanenbaum is bullshit, Minix 3 is very interesting and he is pretty far from stupid in my opinion.

As some who used the prototype wasted cores patchset - it always frustrates me when they say it's BS or slows down their throughput.

The major benefit I gained from the patchset was in something you can really feel performance hits - game servers. I was able to host more without overscheduling of cores and it managed to eliminate consequent spikes. When you disable hyper threaded cores and use this patch and gain better results - you know something's wrong.

Far better than os x and windows.
