Especially those where cache snooping was slow. As well as process affinities if can be of great benefit to have per cpu free lists for memory items and to keep both ends of an active pipe on the same cpu. Of course certain workloads will pump memory resources from one cpu to another - unless you allow for this you get unexpected resource crisis. David -- David Laight: [email protected]
