PgTune — tuning PostgreSQL performance for a given hardware configuration (online version)

Hello, habrovany. Today I want to talk about such interesting things as PgTune.

In 2008 Gregory Smith has created a good tool pgtune. The main objective of this tool was to help newcomers with setting up PostgreSQL. Utility is great, but has a small cons:

the
    the
  • Not updated since 2009 (so the calculations a bit is no longer relevant steel)
  • the
  • Need to download or install from the packages (not a problem in many Linux distributions it is)


So I have created an online version of PgTune. Main advantages:

the
    the
  • Updated count to configuration.
  • the
  • you do Not need to put anything or to pump
  • the
  • Works in offline mode, and it can be used as mobile app


On first boot You will no longer need access to the Internet (only for updates) to use the utility. This is implemented using AppCache technology. That would put it as an app on the iPhone, just log in iOS Safari or Android Chrome and select the menu item "Add to desktop".

And most importantly — utility Open Source.

In conclusion, I want to warn you that this utility is not a "silver bullet" in configuring and tuning PostgreSQL. Many settings depend not only on the hardware configuration, but also on the size of the database, number of clients and complexity of the queries, so that optimally configure the database is only possible taking into account all the system settings and applications (e.g. to consider SSD drives, and if the database fits in memory). But I hope this utility will help you to begin configuring PostgreSQL.

Thank you for your attention. Use on health.
