One measure you can take to improve page loading speed is to enable the caching of static files(images, js and css files). If you have a simple blog with just a few visitors this might result in an improved user experience. A faster website will keep its visitors. On the other side, if you have a very visited website, or if you can get high peaks from time to time, caching static resources can have a dramatic effect, minimizing the server load and keeping the website up.
If you use the classic PHP Hosting like most of the people, you can enable it in Apache modifying the .htaccess file. The changes are pretty simple:
<FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$"> Header set Cache-Control "max-age=2592000, public" </FilesMatch>
The above code instructs the browser to write the cache information in http header for specified file extensions. The browser will parse it and it will know that the file expires in 30 days(2592000). It will store in its cache and for the next 30 days will use the cached version.
