https://community.intel.com/t5/Software-Tuning-Performance/How-to-Record-Calculate-Channel-Stalls/m-p/1104294#M5919 <P>I am trying to determine if/when performance degrades due to congestion on the memory bus. Is there a good way to measure this effect online? For instance, are there counters that record the number of stalls due to congestion on each channel? Do the pcm tools provide any of this sort of information?</P> Thu, 10 Dec 2015 20:38:23 GMT Ben_O_ 2015-12-10T20:38:23Z https://community.intel.com/t5/Software-Tuning-Performance/How-to-Record-Calculate-Channel-Stalls/m-p/1104294#M5919 <P>I am trying to determine if/when performance degrades due to congestion on the memory bus.
