decrease differently with block size for different applications.
other hand, affects performance indirectly by causing contention and hence increas-
ing the cost of other misses. For example, if an application program's misses are
reduced significantly by increasing the cache block size, but the bus traffic is
increased by 50%, this might be a reasonable trade-off if the application was origi-
