Memory performance in AWS

I am doing some benchmarking of memory performance on m3.xlarge and it seems very slow. I am getting about 2.1545Gb/sec for reads and 1.126Gb/sec writes. I get 2x that on my laptop. Is this normal performance?

Just in case, make sure you are not swapping (Memory to disk) at all

swapoff -a

you can check your swappiness here turn-swap-off-permanently

Hope it helps

Not sure what laptop you're running your benchmark on, but you should factor in that anything running on AWS is running in a virtualised (XEN) environment, which is usually going to be slower than the same specs on a physical machine. If performance on AWS is what you're looking for, it might be worth checking out instances like c3.8xlarge or cc2.8xlarge which will should get you as close to bare-metal as possible.

Depending on your business case, you should look at distributing you computing loads on a large number of smaller instances, number that could be scaled according to your own needs.

I hope this helps a little, let me know how I can improve the answer :)
