WHY BOTHER DOING IT?
Faster Joomla = Optimizations
KEEP CALM
IT’S NOT
ROCKET SCIENCE
ü Keep your Joomla! updated
ü Choose extensions wisely
ü Deactivate unused extensions, upgrade used
ü Simplify your templates as much as possible
GENERAL GUIDELINES
Simple Front Page Is Better
ü Fancy stuff – only if you really need it
ü Remove unnecessary large images
ü Use fewer internal/external links – add sitemap
ü Avoid loading content from remote servers
APPLICATION LEVEL OPTIMIZATIONS

Some .htaccess Magic
ü Get the code: http://goo.gl/ze09B
ü How it works: - Etag – Tells browsers that an image/unit does not need to be reloaded
- Expires Headers – Set different expiration dates for various file types
- AddOutputFilterByType DEFLATE – minifies the compiled HTML source code
Some .htaccess Magic
ü The code:
FileETag MTime Size AddOutputFilterByType DEFLATE text/html text/css application/javascript ExpiresActive On ExpiresDefault "now plus 1 hour" ExpiresByType text/css "now plus 1 week“ ExpiresByType application/javascript "now plus 1 week" ExpiresByType application/x-javascript "now plus 1 week”
More Optimizations: Images, CSS & JS
ü Resize images – never upload 2560x1600 pictures
ü Smush your images
ü Minify and combine CSS and JS files
ü Use image sprites
Sounds Nice, How Do I Begin?

ü Photoshop/Fireworks
