Does anyone now how one correctly defines write concern when doing $collection->insert_one()? It seems that I should do something like 

$collection->insert_one({....},
    {
       writeConcern => MongoDB::WriteConcern->new(
            {
                w => 'majority',
                j => 1,
                wtimeout => 10000,
            }
    }
);

That should be waiting till data is copied to majority of hosts in replica set, so it shall be slower, than default write concern. In practice though I get the same speed of writing as with w => 0 and j => 0. Plus replication looses data if I kill primary host. Do I miss something?

I'm using mongodb 3.2.12 and module MongoDB version 1.6.1
