HTTP applications concentrate many performance issues: - They are a common way to let internal & external users access and modify data. - They rely on a delivery chain which contains many elements, which are all performance drivers: browser, workstation, network, front-server, application server, file server, database, images, etc... - They raise specific troubleshooting issues: among others, the end user feedback is based on the concept of page, while most network based performance analysis is based on every transaction / object in the page (html, css, image, script, etc.) This one-hour webinar will enable you to: - Understand the challenges of performance troubleshooting for HTTP Applications. - View a series of concrete diagnostic cases with Performance Vision newest version. You can view the full replay here: http://youtu.be/Lh-yUrabbEs
