There were an ability to back shared memory with hugepages when using <=9.2. I use it on ~30 servers for several years and it brings 8-17% of performance depending on the memory size. Here you will find several paragraphs of the description about how to do it https://github.com/grayhemp/pgcookbook/blob/master/database_server_configuration.md. Just search for the 'hugepages' word on the page. -- Kind regards, Sergey Konoplev PostgreSQL Consultant and DBA http://www.linkedin.com/in/grayhemp +1 (415) 867-9984, +7 (901) 903-0499, +7 (988) 888-1979 gray...@gmail.com -- Sent via pgsql-hackers mailing list (email@example.com) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
