Note that we are not talking about having insufficient memory. In my case (2.4 kernel - ie, 2.6 with swapiness 0%) there is more than enough memory to contain all my working set - it's only because cache is too eager to claim memory that is otherwise in use that non-optimalities occur. -- TimC -- http://astronomy.swin.edu.au/staff/tconnors/ If I'd known computer science was going to be like this, I'd never have given up being a rock 'n' roll star. -- G.
