Ultra-Fast ASP.NET 4.5 presents a practical approach to building fast and scalable web sites using ASP.NET and SQL Server. In addition to a wealth of tips, tricks and secrets, you'll find advice and code examples for all tiers of your application, including the client, caching, IIS 7.5, ASP.NET 4.5, threads, session state, SQL Server 2012 (otherwise known as Denali), Analysis Services, infrastructure and operations. By applying author Rick Kiessig's ultra-fast approach to your projects, you’ll squeeze every last ounce of performance out of your code and infrastructure—giving your site unrivaled speed.
for each control and the size of their rendered content, ViewState and ControlState. 72 CHAPTER 3 CACHING Keep in mind that it is sometimes faster to refetch data from the database for controls such as GridView than to have it sent to the client and back to the server again as ViewState. From Figure 3-3, you can see that just 4KB of ViewState would take around 300ms to send over a DSL connection with a 128Kbps uplink. You can retrieve a lot of data from SQL Server in 300ms, particularly if
they should be. Although there are still a small number of proxies that support only HTTP 1.0, in my experience they tend to be private proxies, rather than public ones. The other main source of HTTP 1.0 requests is likely to be from uncommon spiders or other low-volume corner cases. If I were building a large web site today, unless there was a specific requirement to support it, I would probably just block all HTTP 1.0 requests, due to site-performance issues (such as lack of keepalive),
same method. When the method is called, the arg string will have the value that you set in the VaryByCustom property on the page. The runtime will generate and store different versions of the page for each unique value that GetVaryByCustomString returns (think of the return value as the key for a hash table). In this case, you’re returning the value of a cookie, so the runtime will cache a different version of the page for each value of the cookie. For cases with greater complexity and multiple
queue the image for downloading. Then, in the tag, just use the same filename again. Since the browser should cache the image, it will be downloaded only once. You should use late loading for images that the user wouldn’t consider important or that are below the fold, where they won’t be seen right away. You should use early loading for images that are important to the user and that are above the fold. Browser Caching All components of URLs except the hostname are case-sensitive. Since the
