Didn't you notice a huge drop in performance producing row-buffer conflicts over and over ?
- leghifla 8y agoGood question. Jumping around the memory is clearly not good for throughput. Before the change, the mixing of requests between processes was already detrimental for performance anyway. All I can say is that we needed a fixed bandwidth and it was enough, before or after the change.
