LMBench Read and Write Performace comparison

Other Parts Discussed in Thread: AM5728

Hi,

We are trying to calculate the DDR bandwidth availability for one of our applications on AM5728  and we come across a strange observation that the write throughput (bw_mem-fwr-1mb = 6708.48 MB/s) is more than read throughput (bw_mem-frd-1mb = 3091.22MB/s). 

Reference:

Can anyone help us understand this phenomenon?

Thanks in advance,
Abhiroop
