For user code accessing allocated memory, the data cache is always enabled. However the cache size is limited (currently 8k or 32k), only so many "ways" (partial address overlaps) can be in the cache at one time, and data must first be fetched from memory by an initial load or store access before it will be in the cache. So the first time through a small loop will always be slower.
