  Tutorial: Servlet and JSP performance tuning

Servlet and JSP performance tuning This article describes performance-tuning techniques (PTT) for developing high performance and scalable JSP (JavaServer Pages) pages and servlets. That means building applications that are reasonably and consistently fa

Tutorial Details:

PTT 1: Use the HttpServlet init() method for caching data
The server calls the servlet's init() method after the server constructs the servlet instance and before the servlet handles any requests. It is called only once in a servlet's lifetime. init() can be used to improve performance by caching the static data and/or completing the expensive operations that need to be performed only during initialization.

For example, it is a best practice to use JDBC (Java Database Connectivity) connection pooling, which involves the use of the javax.sql.DataSource interface. DataSource is obtained from the JNDI (Java Naming and Directory Interface) tree. Performing the JNDI lookup for DataSource for every SQL call is expensive and severely affects an application's performance. Servlet's init() method should be used to acquire DataSource and cache it for later reuse:
