Optimizing dynamic pages

Optimizing dynamic pages
These are web pages that change because they are based on a database (such as property pages on real estate websites), instead of static pages that sit unchanged unless their website owner edits them. You can often tell a dynamic website because its URLs end in .asp, .cfm, or .cgi.

1. Change the default database prefix (jos_)
You can set the database prefix when installing your Joomla! Website. If you've already installed Joomla! and want to change your prefix, do the following:
1. Log on to your Joomla! Back-end.
2. Go to your global configuration and search for the database
3. Change your database prefix (Example: fdasqw_) and press Save.
4. Go to phpMyAdmin to access your database.
5. Go to export, leave all default values and press Start. Exporting the database can take a while.
6. When done, select all code and copy it to notepad (or any other text editor)
7. In phpMyAdmin, select all tables and delete them
8. In notepad, do a Search & replace (Ctrl + H). Set the search term to jos_ and change it into your new prefix (Example: fdasqw_). Press "Replace all".
9. Select everything in your notepad file and copy it. In phpMyAdmin, go to SQL, paste the queries and press Start.
2. Remove version number / name of extensions
3. Use a SEF component
4. Use the correct CHMOD for each folder and file
5. Change your .htaccess file
