Dear some consultation, I have a base of about 750 GB in size and we are having problem of slowness in certain views of the application, so I have been seeing it is apparently a memory problem because if I run again the view runs fast, the base is in a virtual server with 24 GB of RAM and 8 GB of shared buffer, with this information how much would you recommend to put a memory in the server thank you very much -- Sent from: http://www.postgresql-archive.org/PostgreSQL-performance-f2050081.html
