I read claims like L2 is not a good place to keep your heavily used data. I do not understand how do you keep your heavily used data in L2. Maybe an example may help me. I need Definition of the heavily used data in Crafty. I need to understand how do you decide that it is the heavily used data( a profiler may tell me how much time I use for a function but I do not know if it can tell me information about time that is used for a specific data structure) and I need to understand how do you tell the computer to keep the heavily used data in L2.
