Use of IndexesUse Indexes with a plan, mistakes that we do..

● Define no indexes, or not enough indexes

● Defining too many indexes

● Running queries that no indexes can be used

‘%test%’

● Check the slow query log (in MySql)

● Use EXPLAIN in Mysql to Check the Query Execution

Path

● Rebuild Indexes : OPTIMIZE TABLE tbl_name

Optimized Caching Alternative 01:

Memcached

http://memcached.org/

● 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

© 2014 Netstarter

● 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.

Redis

Getting the Good of Both -

Netstarter Way● Cache and Full Page Cache - Redis

● User Session Storage - Memcached

○ Key/Value storage system fits sessions

○ Little bit faster than Redis

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
