Advice You - A Perfect Guide for MYSQL and Security - Creating the Best Linux Hosting Environment
There are certain things you must be very careful of when you build your website. Performance of the website is a major factor in its success. This guide will give you a technical overview of your server performance. In this guide I am only concentrating on Linux environment as

2. It supports the fastest script engine PHP.
3. It has the default MySQL database.
4. Its web server is apache, which can be configured with less effort and
