Web Server

Multiple Web Servers make web server

tier highly available

Hardware load balancer distributes

load among web servers

Additional capacity can be added by

adding additional web server nodes

Initial web server count can be decided

based on LIFERAY Portal Performance

High Availability & Scalability of

Application Server Tier

Database

There are multiple options for high availability and scalability

of database tier

Database Clustering

Read/Write Database Separation

Database Sharding

Database clustering depends upon the database provider

and can be implemented independently

Read/Write Database split and database sharding is

supported by LIFERAY Portal



Database Tier

Read/Write Database Separation

Most database support read-write

separation and replication

LIFERAY Portal provides a way to

configure separate read and write

database

Read/write separation of database

benefits from database level

optimization

It also helps scaling database by

separating read and write operations

Data Replication

Database Sharding

LIFERAY Portal offers sharding data for

each virtual portal instance

Sharding enables separating huge

amount of data in comparatively

small instances

This improves performance as well as

scalability of portal

Liferay offers multiple options to store

media gallery data

Depending upon the requirement right

option should be used

Here are recommended options in

sequence

Search Engine

There are multiple options to make the search engine highly

available and scalable

Embedded Lucene search engine with LIFERAY Cluster Link based

replication

This option works in most cases and recommended approach

Integration with Solr based Search engine

If there is a heavy use of search engine in LIFERAY then it is

recommended to integrate LIFERAY with Solr search engine

Integration with Solr based read/write architecture

In case of further optimization Solr’s master/slave feature should be used

LIFERAY provides built in support to configure Solr master/slave design


Search Engine


Architecting following

components can ensure high

performance of LIFERAY

Portal

Caching

Static Resource Delivery

Content Delivery Network

Architecting Portal for High Performance


Caching improves performance

by reducing

Database calls

Expensive object creations

Expensive garbage collection

LIFERAY provides three level of

Cache built in

L1 – Request Scope Cache

L2 – Memory based Cache

L3 – Swap Space Cache

Caching for high performance


L3 Cache Bucket

L2 Cache Bucket

L1 Cache Bucket

LIFERAY Portal uses embedded EHCache for L2 & L3

Cache by default

In clustered environment right cache replication

strategy needs to be used for high performance

LIFERAY Offers following cache replication strategy in

recommended order

Cluster Link based cache replication

RMI Based cache replication

JGroups based cache replication



Centralized Cache Server

High volume caching separate cache server like Terracotta is

recommended

LIFERAY provides built in support for Terracotta based

Caching

For high volume caching it will benefit against cache

replication overhead



Web Accelerator for caching

web resource

For content driven public portals,

it is recommended to cache

whole pages through web

accelerator

Varnish is one of the popular

open source web accelerator

more details on configuration

Delivery of static content like images, css, javascripts, videos affects

response time

Improvement in static content delivery can help improving

performance

Two options to improve static content delivery

Static Content Delivery from Apache Web Server

This option improves overhead of LIFERAY Portal application server in delivering static

resources

Additional deployment step required to copy static resources on Apache Web Server

Content Delivery Network

LIFERAY supports content delivery network built in

CDN improves response time for static content delivery especially for multi region user

base

Static Content Delivery for High

Performance


CONFIGURATION BEST PRACTICES


Disable all servlet filters for unused features

Disable all schedulers for unused features

Disable all unused auto login hooks

Disable counters for unused features

Asset View Counters

Document Counters

Document Rankings

Disable inline permissions if not required

Disable unused Liferay features like Pingback and

Trackbacks in Blogs Portlet

Portal Configuration Best Practices


Web server should be configured to deliver static resources

It reduces overhead on application server

Web server should be configured to add longer browser

cache time in static resource responses

Web server should be configured to compress static

resource responses

Web server should be configured to run required number of

process to meet concurrent user requirement

Web Server Configuration Best

Practices


PORTAL RUNTIME TUNING


Portal runtime tuning involves three step iterative

process

Load generation can be done using tools like Jmeter,

Grinder, Load runner

During the exercise different resources needs to be

monitored
