8. PerformanceONE OF THE OVERARCHING GOALS of this release of ASP.NET was to improve the performance and scalability of applications. The ASP.NET team accomplished this in two ways: by optimizing code paths and improving resource utilization, and by making performance-enhancing features like caching and client callbacks easier to use and manage. This chapter looks in detail at the many new caching features, including declarative data source caching, SQL cache invalidation, and post-cache substitution. We will also cover general performance enhancements and the new client-callback architecture. |
