Performance evaluation of Web Cache
Next we will consider an example of discrete event simulation implemented in CSIM. The example discusses the effect of Web caching on network planning in sense of determining the bandwidth of the access link interconnecting the ISP’s subnet with the internet. This is studied by means of simulations [1]. The latency of a browser retrieving files is studied for given traffic characteristics, numb...
متن کاملReduction in Cache Memory Power Consumption based on Replacement Quantity
Today power consumption is considered to be one of the important issues. Therefore, its reduction plays a considerable role in developing systems. Previous studies have shown that approximately 50% of total power consumption is used in cache memories. There is a direct relationship between power consumption and replacement quantity made in cache. The less the number of replacements is, the less...
متن کاملFLAP: Flash-aware Prefetching for Improving SSD-based Disk Cache
In modern enterprise storage systems, there is a trend that using NAND flash based solid state disks (SSDs) as a second-level disk cache to reduce the slow access to hard disk drives (HDDs) by caching the hot data of HDDs with SSDs. However, using SSDs for both caching and prefetching has rarely been discussed due to the performance penalty caused by unsuccessful prefetching, including garbage ...

متن کاملPerformance Evaluation of Link-Based Cache Coherence Schemes
Large-scale shared-memory multiprocessors rely on private coherent caches by using directory-based protocols. Directory-based protocols preserve network bandwidth by reducing the number of consistency actions. A critical issue becomes how they maintain state information about the set of caches and how they reduce read and write latencies. These tradeo s are studied in this paper. We study two l...
