Just for information: this patchset, applied to 2.6.35-rc6, gives about 20-25% increase in speed/throughput on my desktop system (Phenom 2.5GHz Quadcore, 3 disks) with the tunables set according to what you've used/reported here (the setup with slice_idle set to 0), and it's measurable with fs_mark, too.
After 2 hours of hard testing, the machine remains stable and responsive.
