Recent Presto enhancements (typically land ﬁrst on desktop)Wednesday, November 9, 11

Presto prefetches images included via background-image, -o-border-image, list-style-image, content properties while waiting for more stylesheets to load. Note: we do a super-quick run-through (a sort of selective cascade) to make sure the images will effectively be used. (already in Opera 11.50)Wednesday, November 9, 11

SSL + network improvements: (expect this to land in Opera 11.60, 12)Wednesday, November 9, 11

SSL + network improvements: - SSL False Start: reduces SSL handshake latency. (expect this to land in Opera 11.60, 12)Wednesday, November 9, 11

SSL + network improvements: - SSL False Start: reduces SSL handshake latency. - Strict Transport Security (STS): reminds browser that the given domain should only be contacted over https. (expect this to land in Opera 11.60, 12)Wednesday, November 9, 11

SSL + network improvements: - SSL False Start: reduces SSL handshake latency. - Strict Transport Security (STS): reminds browser that the given domain should only be contacted over https. - Various network speed optimizations. (expect this to land in Opera 11.60, 12)Wednesday, November 9, 11

Our Carakan JS engine internally uses automatic classes to keep track of object properties and their types. Weve recently expanded these classes’ scope and power to also record the layout (or shape) of the objects along with their property types. This improved compact object model allows Carakan to reduce the overhead per object, and the richer type information also enables the generation of better JITed code. (should be in Opera 11.60)Wednesday, November 9, 11

Refactored SVG traverser and improved SVG painting structure, including smarts to optimize for speciﬁc TV use cases. (should be in Opera 11.60, TV deliveries)Wednesday, November 9, 11

Hardware acceleration! - support for OpenGL, DirectX backends. - powers WebGL, 2D canvas, but also all other painting, and even browser UI drawing. (planned for Opera 12)Wednesday, November 9, 11

Opera Turbo Opera Turbo servers act as compression proxy between the user and the website: - non-gzipped content is gzipped - images are converted to WebPWednesday, November 9, 11

Opera Turbo Remember! Look at the X-Forwarded-For header to determine the visitor’s IP address.Wednesday, November 9, 11

Fast panning, without checkerboard:Wednesday, November 9, 11

Fast panning, without checkerboard: - new, dynamic way of drawing content on screen: only visible viewport is rendered.Wednesday, November 9, 11

Opera Mini http://www.ﬂickr.com/photos/nrmadriversseat/5449080917/Wednesday, November 9, 11

Instead of HTTP and HTML, Mini uses a binary format over a binary protocol, with radical reduction of request and responses.Wednesday, November 9, 11

Note: the DOM lives on the server, and hence, dynamic interaction is limited.Wednesday, November 9, 11

Also here, look at the X-Forwarded-For header to determine the visitor’s IP address!Wednesday, November 9, 11
