16. Optimized Caching Alternative 01:
Memcached
● Free & open source
● key-value based object caching
● Configured as 1st level fast cache for Magento
Limitations
● Doesn’t support tag based caching
● Database is used as the 2nd level cache
● No replication method implemented

17. Optimized Caching Alternative 02:
Redis
● Free & open source
● Magento officially recommend Redis
● For Enterprise 1.13.x and Community 1.8.x Redis is
built in.
Why it is so Good?
● Supports tag-based caching/cleanup
● Can work without DB (core_cache/core_cache_tag) tables
should stay empty
● Supports on-disk save and master/slave replication.

18. Getting the Good of Both -
Netstarter Way ● Cache and Full Page Cache - Redis
○ Supports Tag based caching
● User Session Storage - Memcached
○ Key/Value storage system fits sessions
○ Little bit faster than Redis

19. Op-Code Caching
● Accelerates PHP execution
● No side effects other than extra memory usage
● Recommended for Production environment
Which Op-Code Cache?
● APC (Alternative PHP Cache)
● Xcache
● Zend OpCache Bundled with PHP 5.5.0 and later

20. Content Delivery
Network (CDN)
• A network of distributed servers deliver content
based on the geographic locations of the user
• Reduce the load on the main server

21. General Tips
Further Quest for
Performance
