Performance with riak can't reach expected

I benchmark riak's performance using basho_bench in the last days. But the performance is unsatisfying. I have a 2 node cluster, each node running on the same vm(8 CPU, 32 GB RAM). Riak's storage_backend is memory. The total ops could reach 1 with the put command. Can I do something to

Hi Yang, Could you say a little more about what your requirements are, particularly around reliability? For example, what is your n_val, if you are using a 2-node cluster? It would also help to know how many worker processes you have in your basho bench config (the concurrent setting), as

Hi Yang Zhang, To Ruan's point above, there are a number of variables to keep in mind when measuring performance. If you have the option to use a recommended testing framework, please read about basho_bench [1]. If you have to test using whatever you currently use for consistency across systems,

Hi, 1) which client are you using? 2) avg obj/key size & net latency between nodes. 3) are put operations done sequentially or in parallel? 4) what is the round-trip time of one put 5) over which unit of time are you measuring your 1 put operations. 6) bucket/type properties - nval pw w etc.
