Abstract: WEBARM enables end-to-end response time measurement for Web applications through Web page instrumentation WEBARM-agents are a form of mobile code capable of moving with the Web application to monitor response time WEBARM includes the software components responsible for interception and processing of the WEBARM API calls including support for response time measurement, collection, and communication This work provides an assessment of WEBARM instrumentation impact on application response times as well as insights into the design issues involved We first provide a general overview of alternative approaches to Web response time measurement We then consider alternative WEBARM agent software designs, focusing on techniques to store timers across Web page references and communicate logged data to a server Next, we present measurement results for the implementation alternatives to provide insight into the overhead involved with instrumentation and the developed designs Finally, we present conclusions and a description of future work

Web proxy caching: the devil is in the details

- 01 Dec 1998
TL;DR: In this paper, Trace-driven simulation of the modem pool of a large ISP suggests that "cookies" dramatically affect the cachability of resources; wasted bandwidth due to aborted connections can more than offset the savings from cached documents; and using a proxy to keep from repeatedly opening new TCP connections can reduce latency more than simply caching data.

- 12 Apr 1999
TL;DR: The range of situations that can benefit from adaptivity in the context of a set of system and environment parameters is discussed, including Remos (Resource Monitoring System), a system that allows applications to collect information about network and host conditions across different network architectures.
Performance analysis of application response measurement (ARM) version 2.0 measurement agent software implementations
Joseph V. Elarde,G.B. Brewster +1 more
- 20 Feb 2000
TL;DR: This paper introduces alternatives for several important design aspects of ARM agent software that are not specified in the ARM standards documents, and considers the architecture of ARM Agent software, correlator generation and communication, and ARM data storage.
