Fabio Akita

The document discusses techniques for optimizing web application performance, including: - Minifying CSS and JavaScript files using the Juicer gem to reduce file sizes and number of HTTP requests - Serving static assets like images, CSS, and JavaScript files from multiple subdomains to allow the browser to make more parallel requests - Enabling gzip compression and setting long cache expiration headers for static assets with Apache modules - Adding cache busting query strings to asset files to ensure browsers fetch fresh versions when assets change
