Preface
Liferay is the most popular portal based on open standards, written in Java. It was named Leader in Gartner's Magic Quadrant for Horizontal Portals. Many influential sites have been implemented with or have switched to Liferay Portal. The Liferay platform is highly scalable to serve millions of pages to millions of users on all web browsers, tablets, and mobile devices. We, at CIGNEX Datamatics, have implemented more than 200 large enterprise portals using Liferay since 2006. I was leading Liferay Practice at CIGNEX Datamatics with a staff of 240 Liferay experts. We have tuned many Liferay-based sites, and also trained many administrators and developers in Liferay. This book distills the hands-on approach of my project engagements into a concise, practical book.
Liferay Portal Performance Best Practices will explain to you how to implement high-performing, Liferay-based solutions by following various best practices. The book not only explains the best practices in detail, but also provides the detailed instructions to implement them. By following the logical flow of the chapters, you will learn performance-related best practices that should be followed during the architecture, design, development, deployment, and testing phases. You will also learn best practices for conducting performance tuning activities for a Liferay-based solution. By the end of this book you will have the advanced knowledge to implement a high-performing, Liferay-based solution.
What this book covers
Chapter 1, Architectural Best Practices, talks about the Liferay Portal reference architecture. It talks about various architectural options for implementing high-performing, Liferay-based solutions.
Chapter 2, Load Balancing and Clustering Best Practices, teaches you how to implement load balancing and clustering for a Liferay-based solution. It teaches you about various configuration options for implementing clustering.
Chapter 3, Configuration Best Practices, teaches you various configurations for improving performance of Liferay-based solutions. It talks about performance-related configuration options for the Apache web server, the Tomcat server, Liferay Portal, and so on.
Chapter 4, Caching Best Practices, talks about various options related to caching for improving the performance of Liferay-based solutions. It also teaches you how to configure Liferay Portal with the Terracotta cache server.
Chapter 5, Development Best Practices, talks about some of the key Liferay-specific development practices for developing a high-performing, Liferay-based solution.
Chapter 6, Load Testing and Performance Tuning, teaches you how to perform load testing and performance tuning exercises for a Liferay-based solution. It talks about best practices and guidelines related to load testing and performance tuning. It talks about how to monitor various resources during a load testing exercise in order to fine-tune the solution.

Conventions
In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "Instead of using SingleVMPoolUtil, we will need to use the MultiVMPoolUtil class to store and retrieve objects from the cache."
A block of code is set as follows:
/arrows/01_down.png=0,16,16 /arrows/01_left.png=16,16,16 /arrows/01_right.png=32,16,16 /arrows/01_up.png=48,16,16
When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:
package com.connectsam.development;
import com.liferay.portal.kernel.cache.SingleVMPoolUtil;
import java.util.ArrayList;
import java.util.List;
public class SingleVMPoolExample {
public List<String> getTestList(String key){
List<String> listOfStrings = null;New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "In JConsole, navigate to the MBeans tab and then expand net.sf.ehcache | CacheStatistics | liferay-multi-vm-clustered."
