Previous work on workload characterization for Web search systems mainly focuses on the
characterization of user search behavior [4, 7]. In this paper, however, we model workloads …

Web search as a service is very impressive. Web search runs on thousands of servers which
perform search on an index of billions of web pages. The search results must be both …

[EN] The user interaction with the current web contents is a major concern when defining
web workloads in order to precisely estimate system performance. However, the intrinsic …

While Web search engines are built to cope with a large number of queries, query traffic can
exceed the maximum query rate supported by the underlying computing infrastructure. We …

Search is the most heavily used web application in the world and is still growing at an
extraordinary rate. Understanding the behaviors of web search engines, therefore, is …

Commercial web search engines need to process thousands of queries every second and
provide responses to user queries within a few hundred milliseconds. As a consequence of …

Capacity planning studies are suitable for supporting decision making in management and
operation of Web search engines deployed on large clusters of processors. Among many …

In this paper we study three basic and key issues related to Web query processing: load
balance, broker behavior, and performance by individual index servers. Our study, while …

Indy is a new performance modeling framework for the creation of tools for many different
classes of performance problems, including capacity planning, bottleneck analysis, etc …

The performance of Web sites continues to be an important research topic. Such studies are
invariably based on the access logs from the servers comprising the Web site. A problem …
