Riak is not meant to be on a single server. With the default settings, you are writing three copies of every key to disk instead of one. Comparing Riak to Couch on a single server is like comparing apples to oranges. Here is a better comparison of Riak v. Couch http://docs.basho.com/riak/latest/theory/comparisons/couchdb/.
We typically recommend testing Riak out on 5 nodes. Searching riak-users will dig up some ways to adjust the n_val and ring_size to better model Riak on a single node if testing on multiple nodes is not possible. -Jared On Fri, Aug 30, 2013 at 12:07 PM, akonsu <ako...@gmail.com> wrote: > I installed Riak on my development machine (32 bit Lubuntu 13.04), and ran > stress test on it using siege (http://www.joedog.org/siege-home/).
