Memory performance (Score:1)
This is something a lot of people don't seem to get -- CPU and disk are all but free in our era of 2GHz+ chips and terabyte drives, but memory (and cache) are a huge bottleneck. The limiting factors in many programs I write (bioinformatics) are memory and sometimes address space, not CPU time or disk space; and my most frequent source of UI irritation is not waiting for the CPU, but waiting for an application that has been paged out. Yet we see man-years devoted to ever-more-complicated CPU schedulers and
Re:Memory performance (Score:1)
I've seen applications where the best possible optimization was to remove a cache and recalculate a modestly cheap value; many modern processors are fast enough that throwing a few extra cycles in the pipeline is more efficient than paying the price of a processor cache miss.
