There are too many "it depends" issues, especially the hardware, and not least the application architecture sitting on top of it. There's a script in the Message DB codebase that will do some fairly rudimentary read and write performance measures for your Postgres deployment: https://github.com/message-db/message-db/blob/master/database/benchmark.sh https://github.com/message-db/message-db/blob/master/databas... It's run right on the database, so no network I/O or client implementation in the loop - which is inevitably non-representative of "real world" scenarios.
