This document describes performance considerations when developing applications for Domino R5.0 or R4.6. We discuss the following issues in * How to consider performance and capacity when designing and developing a Domino application * How to analyze a Domino application that does not meet its performance and capacity goals * While both platform setup (Domino server and operating system) and application architecture need to be considered when looking at performance and capacity, this book focus on the application perspective. This redbook was written for Domino designers and programmers, customers, IBM Business Partners, and members of the IBM and Lotus community who need a good technical understanding of how to develop applications that scale and perform using Lotus Domino R5.0 and R4.6.
