This book talks about optimizing the performance of your Liferay portal based application through design, coding and system configuration. In the first section, the author talks about aspects in architecture for a better performing site. Then he explains how to cluster multiple Liferay portal instances for a quickly-responding web application. He talks about how to improve performance by configuring the Liferay portal, the application server and the Apache web server. Then he elaborates on the best practices in coding for a fast-running web site. In the last section, the author explains how to do load testing and optimize the number of database connections and cache settings.
Samir Bhatt, the author, has been in the IT industry for 12 years. He has hands-on experience in designing Liferay portal based web applications with excellent performance. He has personally fixed performance issues on web application projects. He is the co-author of a Liferay Beginners Guide book. Samir Bhatt is the right person to write this book.
This book is the first book on performance tuning for the Liferay portal based projects. You may have attended Liferay symposiums or seminars. You may have read Portable Document Format (PDF) documents about Liferay portal performance adjustment. But those are scattered information. This book provides you systematic ways to configure and deliver a Liferay portal project.
The book is a comprehensive book on delivering a Liferay portal project with good performance. It covers the performance topics in architecture, coding and testing. It provides instructions about configuring the Liferay portal, the application server and the Apache web server for better performance. When it talks about caching, it elaborates on cache settings, cache APIs like JGroups and the integration of Terracotta with the Liferay portal.
The book contains much original content. When people configure a cluster environment of Liferay portal instances, they usually use mod_jk or mod_proxy_ajp. This book provides the third way of cluster configuration: using mod_proxy_http. It also contains other Liferay portal configurations that may not be known to many Liferay portal fans.
The author is insightful to put project architecture for performance in Chapter 1 - good performance starts at project design. The author talks about multiple options for designing a quickly-responding web site. For an optimized sizing of the web site, the author asks about the number of concurrent users at the web site. Chapter 1 also mentions that log-in is the most resource-consuming use case in the Liferay portal.
The book has many practical tips for architects, developers and system administrators. Do you know how to merge all the CSS files in a custom Liferay theme before they are delivered to the browser? This is talked about in Chapter 5. How many database connection objects should you keep in your database connection pool? You can get that optimized value through load testing, which is explained in Chapter 6.
The book is written in simple English. The narration is smooth, making it easy for readers to follow the instructions. The instructions are accompanied with screenshots.
On an overall basis, I strongly recommend this book to web application developers, Liferay portal fans and Java lovers.
Who should read this book
A Liferay portal architect should read this book before he does his next Liferay portal project. When his project is a large-scale project or his project involves complicated permission rules, performance becomes a top priority item in his list of tasks. This book will tell him what hardware to use, which technologies to adopt and how the production environment should be set up - this book has provided comprehensive information to help him make such decisions.
A Liferay portal developer should read this book. To write good code for performance, an excellent developer should avoid memory leak, strive to use less memory and access the application server and database server less. He can improve his code quality for performance by taking the advice in this book.
A system administrator for Liferay should read this book. This book contains explicit configuration settings he can copy and paste in his Apache web server, application server and Liferay portal instance.
The book achieves this high rating by being well structured and extremely easy to follow. When alternatives are available he covers this without being sidetracked from a particular chapter or section focus, usually then covering the details of the alternative in a later section. One good example of this is the use of SOLR search engine instead of the default and included Lucene.
This is the first book that I have been able to read and comprehend easily in terms of how to set up load balancing and clustering and all the relevant connections needed to ensure cache and content is updated, once again covering the popular alternatives to standard out of the box Liferay.
In chapter 3 the author covers many of the standard Liferay property settings and describes why they are there and hot to configure or turn them off if not needed, in order to get better performance. Settings such as the auto logins, url filters and so on. This chapter by itself is worth the money in that it serves as a check list of your portal.properties file for operational running and not development.
The final chapter covers performance monitoring especially when doing load testing using scripted test engines but also to help identify bottlenecks in live operation. It is by no means an in depth instruction on the tools used but give the reader enough to get started and then look up individual reference books for more options and interpretation.
In summary this should be essential reading for all staff responsible for deploying and supporting live Liferay installations.
