Slow inserts

I have set up a 5-node test environment to give Riak a test run. I wrote a Python script ( 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 ( reached > 1500 ops/second for significantly bigger values than my benchmark.

Additional information:
* Four of the nodes were not doing anything else.
* n_val=3
* 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.
