Actually, they may well just be optimizing that work for memory, rather than CPU, and could be making some tragic choices with respect to blowing the cache which (on modern machines that lean on L1 and L2 cache a great deal) could lead to worse performance than on a machine that didn't have the large cache in the first place.... I have come to hate L2 cache for so many reasons. It's the primary reason, for example, that hyper-threading hoses our application at work. HT would be a very nice tool, but if you blow the cache you get worse performance than without :-( -- Aaron Sherman <[EMAIL PROTECTED]> Senior Systems Engineer and Toolsmith "It's the sound of a satellite saying, 'get me down!'" -Shriekback
