This conference proceedings contains 26 papers. These papers discuss the latest advances in the theory and practice of computer system performance evaluation. The main subjects are performance analysis of parallel computer architectures, performance of real-time bus scheduling algorithms, load-balancing heuristics and process behavior, queueing network models, performance analysis and modeling of communication systems, probabilistic analysis of database systems, program behaviour and measurement, queueing analysis of fault-tolerant computersystems, and some single server queues problems.

This paper describes our implementation of and initial experiences with DipZoom (for "Deep Internet Performance Zoom"), a novel approach to provide focused, on-demand Internet measurements. Unlike existing approaches that face a difficult challenge of building a measurement platform with sufficiently diverse measurements and measuring hosts, DipZoom implements a matchmaking service instead, using P2P concepts to bring together experimenters in need of measurements with external measurement providers. DipZoom offers the following two main contributions. First, since it is just a facilitator for an open community of participants, it promises unprecedented availability of diverse measurements and measuring points. Second, by offering programmatic access to the entire platform from the experimenter's local computer, DipZoom simplifies staging and execution of complex measurement experiments and lowers the bar for obtaining high-quality measurements.

The measurement, analysis and implementation of a working video server testbed implementing both patching and periodic broadcast algorithms was reported. The testbed consisted of both Linux and Windows-based clients and a Linux-based, application level video server. The underlying system issues were investigated that arose when putting idealized algorithms into practice.
Cerebral palsy is leading cause of physical disability in childhood. This interferes with normal ambulation. Rectus femoris muscle spasticity has been reported to be a cause of stiff knee gait in the patients with cer...

In this paper we develop the first methods to approximate the queue length distribution in a queueing system with redundancy under various service disciplines. We focus on a system with exponential job sizes, i.i.d. c...

We propose a user model that explains the shape of the distribution of file sizes in local file systems and in the World Wide Web. We examine evidence from 562 file systems, 38 web clients and 6 web servers, and find that the model is a good description of these systems. These results cast doubt on the widespread view that the distribution of file sizes is long-tailed and that long-tailed distributions are the cause of self-similarity in the Internet.

Despite the increasing interest in content bundling in BitTorrent systems, there are still few empirical studies on the bundling practice in real BitTorrent communities. In this paper, we conduct comprehensive measurements on one of the largest BitTorrent portals: The Pirate Bay. From the torrents data set collected for 38 days from April to May, 2010, we study how prevalent bundling is and how many files are bundled in a torrent, across different types of contents shared: Movie, Porn, TV, Music, Application, E-book, and Game.
The increasing need for data sharing in large-scale distributed systems may place a heavy burden on critical resources such as file servers and networks. Our examination of the workload in one large commercial enginee...

In order to achieve the unified measurement of the air velocity from subsonic to supersonic circumstance, an analytical method referred to as the equivalent acoustic source, which was only suitable for the analysis of supersonic air current before, is extended to the subsonic case. Systematic analysis demonstrates the essential difference of the air current property between subsonic and supersonic scenario. Finally, a unified measurement model of acoustic particle-velocity vector is introduced. It provides a mathematical basis for us to measure the transonic air velocity via the use of an acoustic particle-velocity sensor, i.e., acoustic vector-sensor.
