That depends on how many arrays you use in your afl. for example, if each field on a record is loaded, it uses up 40 bytes but each array is only 4 bytes * nSize. 1 M of L2 cache will keep 250 bars of a single array, ie 25000 bars will need 10 M of cache. There are roughly 400 bars of 1 min per day session or 2000 bar per week.
