You can always push at that trade-off... Further tuning is on the Linux agenda. Right now we've got a rather fancy implementation of a slow (relativly speaking) but portable algorithm. The most useful useful trick of all will be increasing the pagesize to grow beyond the small pagesize of 4k - for expected significant performance benefits because the the TLB reach will increase but also virtual aliases will go away on about anything but R4000SC returning us to the promised lands of simplicity of cache managment :-) Ralf
