Configure a content cache area
Content cache areas can be shared among servers in the same site. Sharing cache areas among geographically close servers avoids latency delays that could affect the cache performance. Once the content cache area is created for a site it can be mapped to specific virtual server or server instance.
To configure a content cache area
- Right-click on the Sites/<site>/Virtual Servers/<server> instance node in Enterprise Manager and select Properties.
- Select the Content Cache tab from the Properties display.
- Select a content cache area from the Available Content Cache Areas field.
NOTE If the content cache settings are inherited from another object, the content cache will be read-only. To edit the content cache area, select the Override Inherited settings check box.
- Modify the Maximum state elements in memory if desired, as described below.
- Click Apply.
- Maximum state elements in memory
- Designates the number of content elements whose state information is kept in memory.
The default value is 10000.
A content element's state information includes the following information:
- The creation date and time of the content object
- The last modified time of the content element in the cache area
- The state of the element
The approximate size of each content element's state and identification information is 150 bytes.
When setting a custom value, note that setting the value too high uses more server memory to store the content elements' state information, and setting the value too low results in additional disk access to retrieve the state information from the content cache elements.
- NOTE Altering the default value can have an impact on system performance. The higher the number, the more server memory is needed to store the content element's state information; the lower the number, the more disk access is needed to retrieve the state information from the content cache elements.
