Also you should create 1GB swap for VPS (usually double or ~ RAM swap)

The installation steps performed similar HocVPS Script installation guide .

2. Install Zend Opcache

using Zend OPcache aim to optimize and speed up PHP, this is especially important and are required to install the VPS has a large number of people online. Thereby reducing CPU performance and significantly reduce the amount of RAM that PHP uses.

HocvPS Script automatically install Zend OPcache helped you, now just need to adjust the parameters to suit your needs use only.

 nano / etc / sysconfig / memcached

PORT = "11211"
USER = "memcached"
Maxconn = "10240"
CacheSize = "64"

Similarly Zend OPcache above, you should use the tool to track phpMemcachedAdmin adjusted to ensure memory <= 70%, avoid too much redundant RAM (like blogs Learning VPS due WordPress just 64MB RAM for memcached should spend).

In the last step you do not need to install plugin for WordPress WP-FFPC because we W3 Total Cache plugin using the guidance below.

4. W3 Total Cache configuration

To make sure everything works smoothly, please use the W3 Total Cache plugin. I still ordinary or WP Super Cache plugin used because it is simple, easy to use and also very effective ( Watch Me is used). However when used to Memcached, you are required to W3 Total Cache or switch WP-FFPC.
