Hello Mark, As far as I know, MongoDB is able to get better writing performances thanks to scaling (easy to manage sharding). Postgresql cannot (is not designed for - complicated). Why comparing postgresql & mongoDB performances on a standalone instance since mongoDB is not really designed for that ? Thanks for the answer and for sharing, 2016-01-08 17:37 GMT+01:00 Mark Zealey <mark@xxxxxxxxxxxxxxxxxxxx>: > Hi all, I just wrote an article about the postgres performance optimizations > I've been working on recently especially compared to our old MongoDB > platform > > https://mark.zealey.org/2016/01/08/how-we-tweaked-postgres-upsert-performance-to-be-2-3-faster-than-mongodb > > > -- > Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) > To make changes to your subscription: > http://www.postgresql.org/mailpref/pgsql-performance -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
