Improving Application Performance with 3 Simple Functions

Using three, new, simple functions introduced in Adobe ColdFusion 9 -- cacheGet, cachePut, and cacheRemove -- you can significantly improve the performance of your Web-based application. In this session, we'll look at concrete examples of where utilizing the new object-based caching functionality of Adobe ColdFusion 9 can shave seconds (or more) off of each request. The following specific scenarios will be covered:

• populating customer information in session objects
• creating heavily composed objects
• pulling and processing data from external sources/third-party APIs
• building complex queries outside of the database server
• building report tables

Additionally, we'll take a look at prepopulating caches and syncrhonizing cache data across multiple servers, if that's part of your setup. Throughout the session, examples of handling the tough problem of cache eviction will be discussed to help you avoid this common and challenging problem in cache management.
