9:55 AM Insights into WWW Server Performance using Busy-Period Analysis
Pierre Fiorini – BMC Software
Over the last few years the growth of the World Wide Web has been enormous. The number of WWW sites is growing exponentially. WWW applications such as electronic commerce and video conferencing, etc., all increase Internet traffic. One problem faced by WWW server administrators is adequate sizing and planning of their facilities such that they can provide the Quality of Service (QoS) required by end-users. One issue concerning Web server planning arises when attempting to formulate a model that characterizes WWW server performance. The reason is that, in many instances, it has been empirically demonstrated that WWW server file transfer times and sizes are consistent with that of heavy-tailed or power-tailed distributions [2, 3]. A consequence of this high-variability is its potentially enormous impact on the performance of the WWW server. In this paper we discuss approaches on how to model this behavior. The models are subsequently analyzed using steady-state and busy-period analysis. Finally, we conclude by arguing that when heavy-tailed or power-tailed behavior is observed in WWW servers, then busy-period analysis provides additional insight into system behavior; consequently, this aids in WWW server capacity planning.
Pierre Fiorini is a Principal Engineer at BMC Software. His duties at BMC include developing mathematical models for predicting computer system performance. He did his undergraduate work at Colby College and Trinity College, and holds the Ph.D. degree in Computer Science & Engineering from the University of Connecticut where he specialized in queueing theory and computer performance modeling.
11:10 AM Inside Lotus Domino Server
Saqib Syed – BMC Software
Lotus Domino Server has been a leading software for GroupWare applications for a few years now. So far, a detailed investigation of the architectural details of a Domino server from a performance perspective has not appeared. We try to analyze the architecture of Lotus Domino Server 4.6.4 and 5.0. Benchmarks are run on both versions 4.6.4 and ver 5.0 and a brief comparison of performance of these two versions is provided. Some recommendations on software upgrades and users/server are provided for the users based on the results of these benchmarks.
