What speedup could be expected in the steady state by using a merging write buffer instead of a nonmerging buffer when zeroing memory by the execution of 64 bit stores if all other instructions could be issued in parallel with the stores and the blocks are present in the L2 cache?
How many bytes wide should each write buffer entry ?
