Application controlled caching for web servers

Today's web servers must have the ability to deal with large data sets, and their performance mainly depends on the control mechanism of the disc cache. Though the cache replacement algorithms in operating systems generally perform well, application-specific policies can often perform much better. In this paper, we present the application-controlled caching in user space (ACCUS) mechanism for web server disc caching. With this mechanism, an application can schedule the service requests based on the cache status of the requested files to improve its performance so that the system can gain a high parallelism of CPU processing, networking I/O and disc I/O. An application can service the cached files with a higher priority to the ones not cached, which helps reduce the latency caused by disc I/O blocking. Meanwhile, the application can enforce a policy for domain-specific cache management to obtain a higher cache hit ratio. ACCUS is implemented in two web servers of different models, Flash and userver. Despite the great differences in architectures, the empirical results show that both servers can achieve high throughput under heavy workloads with ACCUS enabled. Performance analysis for two other typical web servers, Apache? and Zeus Web Server are also conducted and the results indicate that ACCUS can achieve significant improvement in performance.

Measuring the performance of Internet companies using a two-stage data envelopment analysis model

In exploring the business operation of Internet companies, few researchers have used data envelopment analysis (DEA) to evaluate their performance. Since the Internet companies have a two-stage production process: marketability and profitability, this study employs a relational two-stage DEA model to assess the efficiency of the 40 dot com firms. The results show that our model performs better in measuring efficiency, and is able to discriminate the causes of inefficiency, thus helping business management to be more effective through providing more guidance to business performance improvement.
