By "not doing anything" I meant they were idling apart from the riak/Erlang processes running.
And yes, riak-admin status shows all five nodes according in ring_members according to .

Can you explain what you mean by "Four of the nodes were not doing anything else"?
Does "riak-admin status" show the appropriate nodes in the ring?

I have set up a 5-node test environment to give Riak a test run. I wrote a Python script (<http://pastebin.com/geQ00Ngb>http://pastebin.com/geQ00Ngb) that put 53780 key-values into my cluster. Using round robin, 11 threads inserted these values in ~70 seconds. This means an average of ~750 key-values/second. Is this the expected speed of inserts? It seems quite slow. The Mozilla benchmark (<http://blog.mozilla.com/data/2010/08/16/benchmarking-riak-for-the-mozilla-test-pilot-project/>http://blog.mozilla.com/data/2010/08/16/benchmarking-riak-for-the-mozilla-test-pilot-project/) reached > 1500 ops/second for significantly bigger values than my benchmark.
* Four of the nodes were not doing anything else.
* For every insert, w=1 and dw=0.
* All nodes are using riak_0.14.1-1_amd64.deb and I have not changed any of the defaults settings except Erlang -cookie and -name.
