Performance Gains from Web Performance Optimization Case Including the Optimization of Webpage Resources in a Comprehensive Way
Performance Gains from Web Performance Optimization Case Including the Optimization of Webpage Resources in a Comprehensive Way Juha Vihervaara1, Pekka Loula1 and Tommi Tuominen2 1Pori Campus, Tampere University of Technology, Pohjoisranta 11, 28100 Pori, Finland 2Foredata Oy, Kässäläntie 30, 38200 Sastamala, Finland Keywords: Website, Performance, Optimization. Abstract: Web performance optimization tries to minimize the time in which web pages are downloaded and displayed on the web browser. It also means that the sizes of website resources are usually minimized. By optimizing their websites, organizations can verify the quality of response times on their websites. This increases visitor loyalty and user satisfaction. A fast website is also important for search engine optimization. Minimized resources also cut the energy consumption of the Internet. In spite of the importance of optimization, there has not been so much research work to find out how much the comprehensive optimization of a website can reduce load times and the sizes of web resources. This study presents the results related to an optimization work where all the resources of the website were optimized. The results obtained were very significant. The download size of the front page was reduced by a total of about 80 percent and the downloading time about 60 percent. The server can now handle more than three times as much concurrent users as earlier. 1 INTRODUCTION In spite of the importance of WPO, there has not been so much research work to find out how much Web performance optimization (WPO), or website the comprehensive optimization of a website can optimization, tries to minimize the time in which reduce load times and the sizes of web resources. -

Cdns Extend to Web Performance Optimization and End-To-End Cloud Services 2
For: Application CDNs Extend To Web Performance Development & Delivery Optimization And End-To-End Cloud Professionals Services by Mark Grannan and Philipp Karcher, July 31, 2014 KEY TAKEAWAYS CDN Services Are Evolving To Tackle Mobile And Dynamic Complexity CDN providers are no longer focused on bit pushing services as those services have become largely commoditized. Vendors in the CDN and digital acceleration market are increasingly focused on web performance optimization techniques to meet dynamic content and mobile needs. Parallel Technology Buying Decisions Blur CDN Boundaries Buying CDN services is no longer simple. Web security, cloud storing and hosting adoption, enterprise app complexity, and web analytics needs all factor into CDN purchasing decisions due to the overlaps. Customers need to understand where the overlaps exist to make smart investments. Match Your Performance Needs Against The CDN Landscape’s Four Segments The four market segments include: traditional CDNs that sell bit pushing as a service and aggregate broader capabilities; telco CDNs that add Internet connectivity to the traditional CDN package; cloud platforms that offer basic CDN features to complement storage and compute; and startups that offer caching (primarily) as a feature and focus on newer web performance techniques.

Conclusion Executive Summary The number of companies using internet as their business platform has increased at an exponential rate in the past decade. Business critical web applications need to be monitored in an objective manner to ensure optimal performance. This paper discusses the challenges faced by busi- nesses in monitoring the performance of their web applications, the need for an effective web application monitoring strategy and the Web Ap- plication Monitoring feature of Site24x7. Web Application Monitor 2 Overview E-Commerce has moved beyond its original conception of a cost-saving tool and is now a standard business tool used widely for creating business opportunities. Industry has shown that many new markets for intangible products are being created around changing patterns of how people work and spend their leisure time. This allows consumers to access services such as buying discount coupons, best buy sales, banking, insurance and travel reservations directly from their homes and businesses. E-commerce is being widely used to develop world wide customers in media, entertainment and communication sectors. Banking, online trading and online money transfer services are some of the businesses that use inter- net for high value transactions. What is the core that ensures the success of a web-based business? The answer is obvious; fast loading and fully functional web applications that can be accessed anywhere around the world, 24x7. -
