Opera 11 is four times faster, says the company.
Opera 11.10 for Windows, Mac and Linux also makes a handful of other changes to the browser, notably adding in more HTML 5 support, mail client improvements, an updated rendering engine and better battery management on laptops.
The changes to Opera Turbo and Speed Dial are the most apparent changes in Opera 11.10. The Norwegian company says that Turbo is four times faster than before, and Opera spokesman Thomas Ford said that those speed improvements are likely to filter down to Opera's mobile versions since the improvements were made to Turbo's servers. The gains were achieved in part by adopting support for Google's WebP image format, which resulted in higher image quality in Turbo mode. This still allowed sites to render 35-percent smaller and 15-percent faster than in Opera 11, according to Opera's internal benchmarks.
