Among the hopes for Servo in 2016 are more performance improvements, continue advancing the browser front-end (such as the current browser.html effort), fill in remaining subsystem implementations, bringing the Windows port up to scratch, moving WebRender into production quality, and begin shipping Rust/Servo components gradually within the Gecko engine. Among the performance items on the agenda for Servo this year is CSS support on the GPU, SIMD layouts, DOM wrapper fusion, and more.
