After having more and more performance loss (at least for my system/usage) and no real good solution in view to fix the problems at this location in the kernel, I would prefer to get this thing ripped of as soon as possible. By now I do not see any gain with that piece of code (relative to process/interrupt distribution). And please don?t show me benchmarks - I know what I feel. Userland would be first of all the right place to do any further testing. And please - don?t tell me it?s that complicated to remove this piece of code from source tree.
