In this post I'll introduce some new things I've developed for WSS estimation: two Linux tools, and WSS profile charts. Short durations can be useful for understanding how well a WSS will fit into the CPU caches (L1/L2/L3, TLB L1/L2, etc). But we don't know how much of that is in heavy use, which is what WSS tells us. 16.570 403.66
