Methods and Best Practices for High Performance eCommerce.

By Dmitriy SorokaSystem Architect at Magento, Inc

Performance Improvement Techniques

• Environment– Web Server

Configuration– Data Base Configuration– Accelerating PHP– Additional HTTP

Requests

• Application– Caching– Session Handling– More options

• Scaling– Backend Server– Multiple Frontend

Servers– Multiple Databases

• 3rd party integrations– Integration with Solr

Benchmarks Methodology

• Siege with different concurrencies– 10, 20, 50, 100

• Database Size– Sample data, 10K products, 80K products

• URLs– CMS Page (home page)– URLs List– Checkout

• Results– Requests per second– Orders per hour

ENVIRONMENT OPTIMIZATION

Apache, MySQL, PHP

Apache Configuration

• Apache modules – use just necessary modules• KeepAlive directive• mod_deflate - compress content before

sending it to the browser• Eliminating directory structure scans for

the .htaccess

MySQL Configuration

• innodb_buffer_pool_size– Combined web and db server, 6 GB RAM – 2-3 GB– Dedicated database server, 6 GB RAM – 5 GB– Dedicated database server, 12 GB RAM – 10 GB

• innodb_thread_concurrency– 2 * [numberofCPUs] + 2

• table_cache is the number of tables that can be simultaneously opened by MySQL

• query_cache_size (64 Mb)• query_cache_limit (2 Mb)

Optimization Results

Accelerating PHP

• File system structure optimization• APC• eAccelerator• Zend Optimize• Xcache

Magento Compiler

PHP Accelerators

Additional HTTP Requests

• CSS• Java Script• Images

APPLICATION OPTIMIZATION

Cache, Sessions

Cache Types

Cache Enables vs. Cache disabled

Cache Storages

Memory Based File System Based

APC

Memcached

xCache

eAccelerator

ZendServer Memory

File

Sqlite

Database (MySQL)

ZendServer disk

Storages Benchmark

Full Page Cache (CMS page)

Full Page Cache (urls list)

Session Storage

Files Memcached Data Base

More…

• Flat Catalog• Sales Archive• Backend processes (cron, indexes)• Theme complexity

SCALINGHardware, Web Nodes, Data Base

Hardware

Separate Backend Server

• Data Base• Handle admin users• Process backend activity (cron)• Pre generate Full Page Cache• Handle media queries

Multiple Web Nodes (browsing)

Multiple Web Nodes (checkout)

Data Base

3RD PARTY INTEGRATIONSSolr

Using solr

• Spell checking• Search suggestions• Morphology• Category navigation• Facet navigation
