Liferay Performance Tuning – Complete Optimization Guide

 If your Liferay portal is running slow, facing high memory usage, or taking too long to load pages — this guide will help you optimize performance step by step.

In this blog, you’ll learn:

  • JVM tuning

  • Database optimization

  • Cache configuration

  • Cluster tuning

  • Real-world performance checklist

📌 What is Liferay?

Liferay is an enterprise-grade digital experience platform (DXP) used for:

  • Corporate portals

  • Government platforms

  • BPM integrations

  • CMS-driven applications

Because it’s powerful and modular, proper tuning is essential for production systems.

🔥 1️⃣ JVM Performance Tuning

Liferay runs on JVM, so memory configuration is critical.

Recommended JVM Settings:

-Xms4g
-Xmx4g
-XX:MaxMetaspaceSize=1024m
-XX:+UseG1GC
-XX:MaxGCPauseMillis=200

Why?

  • Equal Xms and Xmx prevents heap resizing

  • G1GC improves garbage collection

  • Metaspace avoids classloader memory issues

📷 JVM Memory Monitoring Example

Use tools like:

  • JVisualVM

  • JConsole

  • Prometheus + Grafana

⚡ 2️⃣ Database Optimization

Liferay is DB-intensive. Poor DB tuning = slow portal.

Best Practices:

✔ Use PostgreSQL or MySQL (Production ready)
✔ Enable connection pooling (HikariCP)
✔ Optimize indexes
✔ Increase DB connection pool size

Example (portal-ext.properties):

jdbc.default.maxActive=100
jdbc.default.maxIdle=20

🚀 3️⃣ Enable Caching Properly

Liferay uses Ehcache by default.

Improve Performance:

  • Increase entity cache size

  • Tune finder cache

  • Enable multi-VM cache in cluster

Check:

ehcache.multi.vm.config.location=/ehcache/liferay-multi-vm.xml

📷 Liferay Cache Architecture

🌍 4️⃣ Cluster Configuration (Production)

For high availability:

✔ Use multiple Liferay nodes
✔ Configure shared DB
✔ Enable sticky sessions (or Redis session store)
✔ Use load balancer (Nginx / HAProxy)

Example architecture:

  • Load Balancer

  • 2–3 Liferay Nodes

  • Shared Database

  • Shared Document Store (S3/NFS)

⚙️ 5️⃣ Disable Unused Modules

Unused modules consume memory and CPU.

Go to:

Control Panel → Apps → Manage Apps

Disable:

  • Unused marketplace apps

  • Demo features

  • Unused connectors

📊 6️⃣ Indexing & Search Optimization

If using Elasticsearch:

✔ Increase heap size
✔ Optimize shard count
✔ Run reindex during off-peak hours

📷 Liferay + Elasticsearch Setup

🧪 7️⃣ Thread & Connector Tuning (Tomcat)

Edit server.xml:

maxThreads="300"
acceptCount="100"
connectionTimeout="20000"

This improves concurrent user handling.

📋 Production Performance Checklist

✔ JVM heap properly configured
✔ DB indexed and optimized
✔ Caching tuned
✔ Elasticsearch optimized
✔ Clustering enabled
✔ Load balancer configured
✔ Unused modules disabled

🎯 Conclusion

Liferay performance tuning requires optimization at multiple layers:

  • JVM

  • Database

  • Cache

  • Search

  • Cluster

  • Application modules

Proper tuning can improve portal performance by 40–60% in production environments.

Scopes of Signal in jBPM

Image
💡 Introduction Signals in jBPM 7 are a core part of event-driven workflow design. They allow asynchronous communication between process instances, making it possible to start , interrupt , or coordinate processes without direct linking. However, signals can have different scopes , which define how far the signal travels and who receives it . Let’s explore the four available scopes in detail: 🔹 Process Scope 🔹 Default Scope 🔹 External Scope 🔹 Project Instance Scope 🧩 1️⃣ Process Scope 📘 Definition Process scope signals are local to a single process instance or its child subprocesses . They are not visible outside that instance hierarchy. 📋 Use Case Used for communication inside the same process , like triggering subprocesses or event sub-processes. 🖼️ Process Scope Example Below is an example of a simple process-scoped signal. Only this process (or its subprocess) will catch this signal. ⚙️ 2️⃣ Default Scope 📘 Definition The default scope ...

OOPs Concepts in Java | English | Object Oriented Programming Explained

Image
🔹OOPS (Object Oriented Programming System) in Java Object-Oriented Programming (OOPS) is a programming paradigm that uses classes and objects to design software. It simplifies development and maintenance by applying key concepts: 📌 Class: Class   is a user-defined data type which defines its properties and its functions. Class is the only logical representation of the data. For example, Human beings in an organisation is a class like Employee. The age, name, department, salary etc. of a human being/employee are its properties, and the jobs performed by the employees in an organisation are known as functions.  The class does not occupy any memory space till the time an object is instantiated. A class is a user-defined data type that defines properties and functions. For example: Class: Employee Properties: name, age, salary Functions: work(), attendMeeting() A class does not occupy memory until an object is created. ...

jBPM Installation Guide: Step by Step Setup

  jBPM Installation Guide – Step by Step for Beginners If you are starting with jBPM (Java Business Process Management) , the first step is to set up your environment. In this guide, we’ll walk through how to install jBPM, configure it, and run your first business process. 🔎 What is jBPM? Before we dive into installation, a quick recap: jBPM is an open-source Business Process Management (BPM) suite , written in Java, that allows you to model, execute, and monitor workflows using BPMN 2.0 standards. It can run standalone , embedded in applications , or deployed on a Java EE server . 🖥️ Prerequisites Before installing jBPM, make sure you have: Java JDK 11 or later (Java 17 is commonly used) Maven 3.x (for building and managing dependencies) Git (optional, if you want to clone sample projects) A Database (H2, MySQL, PostgreSQL, or Oracle) – jBPM ships with H2 for testing At least 4GB RAM (8GB recommended for Workbench & KIE Server) 📦 Download ...
