This object sets the default cache timeout, in seconds, applied to any MIB module data cache entry that doesn't have its own override, defaulting to 5. Admins raise this to reduce backend polling load on the agent for infrequently changing data, or lower it for data that needs to stay fresher. Setting this to 30 makes cached MIB data valid for 30 seconds by default instead of the standard 5, reducing how often the agent needs to re-fetch underlying data.
