It turns out I got better throughput by using it. Basically it adopts a strategy similar to the asynchronous couch_file Damien described in this thread: http://mail-archives.apache.org/mod_mbox/couchdb-dev/201106.mbox/%3c5c39fb5a-0aca-4ff9-bd90-2ebecf271...@apache.org%3E Here's a benchmark with relaximation, 50 writers, 100 readers, documents of 1Kb, delayed_commits set to false and 'info' log level (default): http://graphs.mikeal.couchone.com/#/graph/9e19f6d9eeb318c70cabcf67bc013c7f The reads got a better throughput (bottom graph, easier to visualize).
