It can't be said enough times but the number one thing you can do to ensure that you are getting true performance (not to mention redundancy) is to use different physical hardware for each of your nodes. Under no circumstances should you have more than one VM (one logical node in a Riak cluster) on the same physical hardware. Also, use multiple connections/threads/parallelism/whatever on client side and be sure to hit all the nodes in the cluster haproxy roundrobin-esque when writing to Riak. Everything else is in the noise.
