As a drawback, there is a correlation between the associativities of L1 and L2 caches: if the L2 cache does not have at least as many ways as all L1 caches together, the effective associativity of the L1 caches is restricted.
Nevýhodou je vzťah medzi asociativitami cache L1 a L2: ak nemá L2 cache aspoň toľko ciest, ako všetky cache L1 spolu, efektívna asociativita L1 cache je obmedzená.
