&gt; and the performance of an SCM (hundreds of thousands of I&#x2F;O operations per second) is such that one or more entire many-core CPUs are required to saturate it.<p>So, we are getting a lot of data, but latency is still killing. (Even more taking into account that this thing has a few stages of pipeline inside.)<p>Anyway, our CPU is getting distributed nearer IO and memory. We are going to get NUMA machines, everything points at it.
