'''- the cache line only contains one piece of data with the rest being completely emptypadding'''

This is incredibly inefficient. The whole point of the cache is to improve performance by contain relevant data We want to minimize cache misses. In practice, but by hogging valuable cache space this reduces the scheduler will be juggling many threads with their own data that may or may not be related to this program. By padding out effectiveness of the cache line. If we had a more complex program, we are hogging this valuable space and are forcing could have tons of other data the thread could have fit on the same cache misses to occurline.
