Changing the size of the RAM cache

Content Gateway provides a dedicated RAM cache for fast retrieval of popular small objects. You can increase the RAM cache size for better cache hit performance.

Warning: If you increase the size of the RAM cache and observe a decrease in Content Gateway performance (such as increased latencies), the operating system might require more memory for network resources. Return the RAM cache size to its previous value.

Steps

  1. In the Content Gateway manager, go to the Configure > Subsystems > Cache > General Cache Configuration tab.
  2. In the Ram Cache Size field, enter the amount of space (in bytes) you want to allocate to the RAM cache. Although the user interface will accept larger values, do not exceed 256 MB.
    The default size is 104857600 (100 MB).
  3. Click Apply.
  4. Go to the Configure > My Proxy > Basic > General tab and click Restart.
