But is this swap_readahead justified by spacial locality? And is the read_ahead amount dynamically adjusted according to the locality property exhibited? And in situations when the memory is already under pressure, would read ahead activity cause more swapping? regards jean __________________________________________________ Do you Yahoo!?
