Abstract

Object-based caching is a natural design choice for an object-based application and also offers the potential of improved memory utilization. However, in comparison to page-based caching, an object cache may introduce additional disk reads. These installation reads are required to install modified objects onto their corresponding disk pages. We propose a new operating system service that significantly reduces the cost of installation reads. This opportunistic installation service allows applications to benefit from an economy of scale available in scheduling a large pool of asynchronous disk reads.
