Web development is not always at the top of the list of web hosting industry topics, but there are plenty of instances where the type of development or design used on a site directly or indirectly affects its performance and security. In blog hosting, a successful site can expect high volume traffic that can impact database performance. A sound site design can make it easier to maintain and more efficient.
A theme framework is a theme system designed for WordPress that already has the essentials in place. It means that you can still build a custom theme with your own design, but do not have to worry about developing key code from scratch. For example, a theme framework may have a layout system in place or may even allow you to easily select from a list of layout options. This reduces the amount of PHP coding you might otherwise have to do to get a theme functioning the way you want it.
From a security perspective, a theme framework may offer enhanced security features and have the benefit of being tried and tested on actual sites. For performance, theme frameworks also have the benefit of being tested and run in production environments, which will reduce the amount of trial and error you will have to perform to fine-tune your theme. Moreover, a theme framework will reduce the amount of time you have to spend on theme development and can allow you to deploy multiple sites quickly and easily.
When starting a WordPress blog, design and development may not be at the top of your list when it comes to optimization, but a theme framework can definitely help you streamline your development process. With only a few tweaks, you can have your site running at an optimal performance and security level.
