Can you give a little more detail about the kind of information you’d like from the hardware?

  How much time does each CPU core spend running/waiting for L1/L2/L3/DRAM? How often are those stalls due to cross-core contention for the same bit of memory? Which execution units are in use? What's the limiting factor on throughout? That's what I can think of in the first two minutes, anyhow. It all comes down to the last one.

    Intel CPUs provide a crazy amount of performance counters. I bet that the numbers you want are in there somewhere. Look into the perf tool.

      Alas, I'm using AMD.

  Prob too easy to ask here, but can I get a list of pending syscalls sorted by age?
