One of the most asked question related to OpenX ad server is: "How much load will OpenX place on my server?"
At the first place OpenX shouldn't be installed on shared hosting.
It's for sure that you will need to make some experiments in order to realize what configuration or hosting provider are the best solution for you. Luckily, OpenX ad server is free to use and it doesn't need to be licenced so you are free to use it on many machines at the same time.
OpenX, as a really great free and open source ad server, has capability to prevent the same banner showing up more than once on a page.
For this to achieve, you have a couple of options during generating invocation code for a zone:
- Don't show the banner again on the same page
- Don't show a banner from the same campaign again on the same page
These options are located below the main invocation tag. Select any of the options depending on your needs and click Refresh for generating new invocation tag.
OpenX supports two storage types for banners: SQL storage and webserver.
- SQL banners are located in the database itself
- Webserver banners are located in folder on the server's file system
The question is what storage to use for your OpenX installation, SQL or Webserver banners?
We suggest using web server to keep and deliver your banners because it will work much faster. SQL storage OpenX banners take up space in the database and make it slower and somehow overbloated.
OpenX is very advanced ad serving system and it supports two storage types for your banners: SQL storage and webserver.
In order to move OpenX banners from SQL database storage to webserver folders follow the steps below:
1) Go to Settings -> Maintenance
2) Choose Storage option on the Choose section: menu
3) After page refreshing, click the "Move images stored inside the database to a directory" link
Many users ask: "How to view graphs of OpenX statistics?"
Luckily, starting with v2.4 OpenX support this feature. Note that GD extension for PHP should be loaded on your server previously.
GD is a library that is used for images processing and if you do not have it the graphs couldn't be created. GD library is common on hosting providers but check with hosting support whether your server support it.
