Cache

The Cache page of the Administration Perspective offers an overview of and information on all items currently stored in the system's cache which is specially useful when setting up the system's server input buffer size.

The information called from the database is stored in the server input buffer and can be accessed quickly when required. This improves the system's performance as it is less time-consuming than repeatedly calling the database.

Keep this in mind when specifying the maximum size of the server input buffer in the Processes & Usage page. The value depends on the memory that is available on your computer.

To work with this page, access the Administration perspective and click Cache.

In the toolbar, the buttons Export and Refresh are available by default. These buttons allow you to refresh the content of the table and export it as a CSV file.
