Overall DB size approaches 35GB, and this is the largest table. The machine is a MacBook Pro with an SSD.\r\n\r\nThere are no indexes on the table, the table has soft durability, and I expected a consistent write speed, pretty much regardless of table size. I am surprised by the 8x decrease I'm seeing.\r\n\r\nNothing is CPU-bound, system stats show RethinkDB writing quite a bit (to be expected), and *reading* a lot (which I found puzzling). In fact, the process is reading much, much more than it is writing.\r\n\r\nIf this is to be expected, I think it might be worth considering mentioning it in the documentation, perhaps suggesting configuration changes.\r\n"},"comment":{"url":"https://api.github.com/repos/rethinkdb/rethinkdb/issues/comments/222795394","html_url":"https://github.com/rethinkdb/rethinkdb/issues/5805#issuecomment-222795394","issue_url":"https://api.github.com/repos/rethinkdb/rethinkdb/issues/5805","id":222795394,"user":{"login":"jwr","id":38015,"avatar_url":"https://avatars.githubusercontent.com/u/38015?v=3","gravatar_id":"","url":"https://api.github.com/users/jwr","html_url":"https://github.com/jwr","followers_url":"https://api.github.com/users/jwr/followers","following_url":"https://api.github.com/users/jwr/following{/other_user}","gists_url":"https://api.github.com/users/jwr/gists{/gist_id}","starred_url":"https://api.github.com/users/jwr/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jwr/subscriptions","organizations_url":"https://api.github.com/users/jwr/orgs","repos_url":"https://api.github.com/users/jwr/repos","events_url":"https://api.github.com/users/jwr/events{/privacy}","received_events_url":"https://api.github.com/users/jwr/received_events","type":"User","site_admin":false},"created_at":"2016-05-31T19:32:30Z","updated_at":"2016-05-31T19:32:30Z","body":"I explicitly created the table with soft durability, `insert` gets batches of 1024 documents and I do wait for it to complete before issuing the next one."}}
