1. The hot part of the data decides the cache result, so the sizing report measures the access depth and the flat pattern removes the caching advantage in that characterization.
2. The hot part of the data decides the cache result, so the sizing report measures the access depth and the flat pattern removes the caching overhead in that characterization.
3. The hot part of the data decides the cache result, so the sizing report measures the access skewness and the flat pattern removes the caching advantage in that characterization.
