is their a "top" for the traffic on the memory bus? kinda like\n"netstat" for IP packets, but monitors the transfer rates to/from RAM\ninstead?\n\ni'm trying to optimize the performance of a custom memory-intensive\napplication, and wondering whether the bottle neck is the memory bus.\nit would be nice to know what fraction of the memory bus throughput is\nbeing utilized, and hence whether it'd be worth reconfiguring the\nmemory sticks to be matched.\n\nrelatedly, when an instruction causes the CPU to wait for memory, to\nwhat process are those wasted cycles attributed? let's say RAM is\nreally slow and half of the CPU cycles are spent just waiting for the\nregisters to load. does "top" then report 50% for that process,\nexcluding those idles cycles? or does it report 100%, and include\nthem?\n\nthanks.
