Except that a working prototype of plugsched exists and functions exactly as advertised. I understand that modules can be loaded and unloaded, where as other aspects of the core kernel can't just load/unload as the kernel is running, but the cpu scheduler could be selected at boot via a command line, or as a kconfig option when compiling like the io scheduler. And while the io team may feel that it would be best to have one scheduler that worked well under all circumstances, often this can't simply be the case. Benchmarks over the years seem to suggest that different schedulers work different for different situations. In that regard, choice does seem to be nice. CFS is apparently better in its simplicity, however others are reporting that SD still provides benefits for 3D gaming. Perhaps there are instances where even more schedulers like nicksched might be the most appropriate solution. -- T. J. "In the beginning the Universe was created.
