Magento Apc and Memcached Speed up Magento

I hear a lot of time that people complaints about "Magento is very slow". In my opinion Magento is not a good solution if you are hosting it in a Shared environment, If you've a dedicated server then YES, use it otherwise just use baby e-commerce software available online. This article will focus on configuring and using APC and/or Memcached. I am sharing my local.xml file. Look for <cache>, But before you even do any of that, you need to make sure you've Memcached & Apc installed and configure. Revision Feb-15-2016 The (last) version 5.1.2 of APCu don't support PHP5 (only PHP7) so you need to set a specific version instead of beta tag :

sudo apt-get install php-pear php5-dev make libpcre3-dev php5 memcache memcached php-pear

pecl install apcu-4.0.10
&& echo extension=apcu.so > /usr/local/etc/php/conf.d/apcu.ini
