Copies of disk data pages in RAM can't be a bad thing, as long as they are not 'dirty' (unrepatriated to their media page)! I am amazed it took so long. Is there such a thing as too much RAM, other than to a reliability model?

NAME
Cache::Object -- the data stored in a Cache. DESCRIPTION
Object is used by classes implementing the Cache interface as an object oriented wrapper around the data. End users will not normally use Object directly, but it can be retrieved via the get_object method on the Cache::Cache interface. SYNOPSIS
use Cache::Object; my $object = new Cache::Object( ); $object->set_key( $key ); $object->set_data( $data ); $object->set_expires_at( $expires_at ); $object->set_created_at( $created_at ); METHODS
new( ) Construct a new Cache::Object. PROPERTIES
(get|set)_accessed_at The time at which the object was last accessed. Various cache implementations will use the accessed_at property to store information for LRU algorithms. There is no guarentee that all caches will update this field, however. (get|set)_created_at The time at which the object was created. (get|set)_data A scalar containing or a reference pointing to the data to be stored. (get|set)_expires_at The time at which the object should expire from the cache. (get|set)_key The key under which the object was stored. (get|set)_size The size of the frozen version of this object SEE ALSO
