Study of Reactive Solutions for Web Application Performance Enhancement during Overload Charulata

In today’s world, almost all of the E-commerce websites or applications are available over the Internet. Such websites are often faced with incoming load of requests that exceeds their capacity, i.e. they are subjected to overload. Most existing web applications show severe drop in throughput and thus degraded performance at high overload. There are multiple reactive solutions being suggested for such overload situations to enhance the performance of the web servers viz. Enhancing the caching ability at the web server, applying compressed caching for the underlying OS, applying optimum timeout for the TCP connections, effective overload handling etc. The approach taken for this project is to enhance the web server performance by effective overload handling (overload detection, control etc) This paper attempts to make a survey of the available suggestions / solutions about web server performance enhancement. It also comments on the advantages and limitations of these suggestions/solutions.
