This trend clearly reveals the motives of the SPEC'95 benchmark designers to exceed the capacity of modern first-level caches. Even a relatively large cache size of 256KB leaves over 95% of the internest capacity misses for software techniques to attack.
While the total gap amount has no impact on first-level cache misses, it does have an effect on higher levels of the memory hierarchy.
However, we must guarantee that the data updates the first-level cache only when the informing load operation commits.
