-
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.
