A while back I suggested altering those bits, but that was turned down: https://lkml.org/lkml/2013/3/1/350 Are there any numbers available on how enabling these features impacts the system? I'm a little bit concerned of always enabling them unconditionally, in case it increases latency for some use cases. I think I'd prefer the DT approach, unless the impact is reported to be negligible - which it likely is, I guess.
