Group to measure cache transfers between L1 and Memory. Please notice that the
|
|
L3 to/from system metrics contain any traffic to the system (memory,
|
|
Intel QPI, etc.) but don't seem to handle anything because commonly memory read
|
|
bandwidth and L3 to L2 bandwidth is higher as the memory to L3 bandwidth.
