But Volker, if it takes me an hour to decrapify my kernel config and make it faster, it will probably take 1000 years for those speed improvements to pay off. If I had unlimited time then I would love to read that book. I really LIKE the idea of decrapifying my kernel config. But realistically, any time I spend on it is time wasted, for which no difference will be appreciable. Stroller.
