WHY MAGENTO OPTIMIZATION

Why Magento Optimization• Various studies and our own experience shows that the overall

performance of Magento is slow

• Optimization is required to speed up Magento

• Below is a chart showing the research outcomes for Magento performance without optimization

A comparison of Magento performance before optimizationand after optimization

WHY DOES PERFORMANCE MATTER?

WHY DOES PERFORMANCE MATTER?

• 1 Second delay can cause 7% drop in conversions• Nearly 1/2 of users expect 2 second or less page load time and

they tend to abandon if not loaded in 3 seconds• 79% of shoppers say they won’t return if performance is poor• 44% say they would tell a friend about their poor experience• A Bad Experience Will Drive

– 46% of users to competitive sites– 35% are less likely to visit a problem site on any platform– 33% are less likely to purchase from that company

WAYS TO OPTIMIZE MAGENTO

Ways to Optimize MagentoChallenges & Solutions

• Large number of JAVASCRIPT and CSS

• Slow performance due to multiple associated tables

• High number of database log tables

• Slow performance due to image loading

• Improve performance with caching

• Cloud Server

LARGE NUMBER OF JAVASCRIPT & CSS

Large number of JAVASCRIPT & CSS• Large number of JAVASCRIPT and CSS creates higher no. of HTTP request.

• Response time will go on a higher side because of higher no. of HTTP request and system will be slow.

SolutionMerge CSS and JAVASCRIPT files into single file:

• In the Magento Admin, go to System > Configuration > Developer.

• Under "Javascript Settings", change "Merge Javascript Files" to YES.

• Under "CSS Settings", change "Merge CSS Files" to YES.

• Clear the cache.

Solution

SLOW PERFORMANCE DUE TO MULTIPLE ASSOCIATED TABLES

Slow performance due to multiple associated tables

• One of the main issues with Magento sites running slowly, is a database that has become large and difficult to use for sending/retrieving data from.

• The model Magento uses to store customer and product data results in longer than average SQL queries and more reads.

• Enabling the Flat Catalog option for Categories and Products will merge product data into one table, therefore improving performance.

SolutionEnabling Fat Catalog:

• Login to administration area and go to - System > Configuration > Catalog

• Under "Frontend", change "Use Flat Catalog Category" to yes

• Under "Frontend", change "Use Flat Catalog Product" to yes

• Clear your Magento cache

HIGH NUMBER OF DATABASE LOG TABLES

High number of database log tables• Higher number of database logs creates higher response time in system• Below is the table that are populated due to logging feature of Magento

SolutionDatabase log cleaning using Magento administration• In Magento administration go to System > Configuration

• In the left menu under Advanced click on System

• Under "Log Cleaning", change "Enable Log Cleaning" to YES and configure the Save Log days as per your requirement

• Click "Save Config"

SLOW PERFORMANCE DUE TO IMAGE LOADING

Slow performance due to image loading

• There are large number of images in any ecommerce store.

• On an average a product has more than 3 images and number of products can be unlimited.

• So its very necessary to optimize the images used in Magento store.

• Optimization of images prevents the system from higher response time.

• Choose the correct format for the image - JPG, GIF, PNG8, PNG24

• JPG is great for photographic images

• GIF largely replaced by PNGs, but still sometimes a viable option for small patterns and textures

• PNG combines some of the best qualities of both and with PNG24 supports true transparency

IMPROVE PERFORMANCE WITH CACHING

Improve performance with caching• Setup your admin for maximum performance.

• These are the settings that will significantly speed up your Magento installation: Navigate to System > Cache Management and enable all cache types

• Below is the default caching provided by Magento

• Enabling caching option that Magento provides is not enough

• So we need to use 3rd party caching extension for full page caching

• Example: Nitrogento (http://www.nitrogento.com/) First install the extension

Drawback of using full page caching :

Enabling caching of every block with nitrogento causes different issues as below-

• Caching of Price block shows incorrect price for various products

• Wrong data in checkout processes

Implement Varnish

• Why Varnish– HTTP Accelerator– Caching reverse proxy– Load Balancer– Fail over system

Before & AfterBefore Varnish

After Varnish

Extension Required : Turpentine- Varnish Cachehttp://www.magentocommerce.com/magento-connect/turpentine-6332.html

Install and Configure Varnish• Add the Repository
