摘要： A computerized method, system and computer program product for managing an object store is disclosed. An exemplary method includes the the steps of: collecting performance statistics about storage repositories from which an object(s) can be retrieved; retrieving an object from a storage repository, in response to an object reference; determining a reference probability (RFP) for the object; determining and associating a replacement penalty (RPP) with the object wherein the RPP is based on the one or more performance statistics and the RFP; and storing the object and an associated RPP for the object. The storage repositories could be locally attached devices, network sites, and/or remotely attached devices. If there is insufficient space in the object store for a new object, an object(s) can be replaced with the new object based on the associated RPP of the cached objects. Alternatively, the resolution of one or more objects in the object store can be reduced until sufficient space is available. The RPP determination is preferably based on the RFP for the object and performance and/or usage statistics. Examples of the performance statistics include: availability; size; latency; and bandwidth. An example of the usage statistics includes statistics on time delays (D) associated with abort requests made via the Internet, for example, using a browser. The RPP could include an annoyance function for a specific requester or set of requesters by instrumenting the browser STOP function and analyzing time interval statistics associated with its usage.
