Image Compression: Images were downsampled and converted to lower-quality JPEG or WebP formats on the server before transmission. Users could toggle image quality settings to save further bandwidth.
OBML Formatting: Standard HTML text is verbose. By converting the layout into a binary format (OBML), structural data was stripped of redundant white-space and tags, reducing the payload size significantly.
Protocol Optimization: The communication between the client and the Opera proxy was optimized for low-bandwidth environments, maintaining persistent connections to reduce TCP handshake overhead.
