Bingo. The way to address memory latency is by increasing bandwidth and increasing parallelism to use it -- thus amortizing the latency. HT is one of many ways to do this. If systems are to grow faster at a rate better than memory speeds, then plan on more parallelism, not less. -Len - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
