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 mak

Re: Performance with riak can't reach expected

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.
