Micro-Evaluation of Flash Server Arif Selcuk Uluagac (auluagac+) Nawaporn Wisitpongphan (nawaporn+) FLASH is a portable web server that is based on asymmetric multiprocess event -driven (AMPED). AMPED uses single master process that is responsible for all in teraction with clients and CGI applications along with helper processes that are responsible for all blocking I/O operations. In addition, FLASH makes extensive use of three types of caches to enhance its performance. According to the paper, 'FLASH: An efficient and portable Web server' by Vive k S. Pai, et al., performance evaluation of FLASH server has been shown to perfo rm better than well-known servers like Zeus and Apache. All of the simulations w ere based on request for static contents. However, majority of web traffic today is generated by request for dynamic contents. In order to justify whether FLASH is better than other servers, we think that it is very important to have a more realistic analysis of the FLASH server. What we plan to do is to: 1. Run the server on two different OS; Solaris and Linux. 2. Get a micro-evaluation for dynamic contents. 3. Overload FLASH using S-Client.("Measuring the Capacity of a Web Server", by Gaurav Banga and Peter Druschel) 4. Compare the results to Zeus and Apache, repeating steps 1-3.
