…I checked, Intel's MSRs ( https://en.wikipedia.org/wiki/Model-specific_register ) allow Intel PCM ( https://github.com/intel/pcm ) to work, are indeed used to profile, or "measure performance" (sorry if my vocabulary is not the most…

…Forgetting this tool-space, but at least some of these tools can make use of that hardware: https://github.com/intel/pcm https://github.com/andikleen/pmu-tools

…there's stuff like Intel PCM that can pull super fine-grained telemetry direct from the CPU/chipset https://github.com/intel/pcm . Only used it to confirm that we got NUMA affinity right so far - nothing crazy.

…on certain instance types/sizes you get access to virtualized counters (vPMU). See Q11 here https://github.com/intel/pcm/blob/master/doc/FAQ.md#q11 or tables here https://www.intel.com/content/www/us/en/developer/articles/t... dunno about…

…Linux tools can show you memory bandwidth usage easily (maybe perf), I know we use Intel PCM ( https://github.com/intel/pcm ) and AMDuProfPCM ( https://www.amd.com/en/developer/uprof.html )
