Materialized view vs. view

[Job <Job@xxxxxxxxxxxxxxxxxxxx>]

Hi guys,

 

i am making some tests with a massive number of "select" queries (only for reading datas) on a view and a materialized view.

We use Postgresql 9.6.1 on a 64bit server.

 

Only for "select" queries, which one is faster and less expensive as resources cost?
The view or the materialized view?

The view has about 500K lines.

 

Thank you!
