Carakan's Speed Improvements

March 3, 2010 · by Espen André Øverdahl

Carakan is Opera's new JavaScript engine. Many of today's Web applications depend heavily on JavaScript, and we're developing what will be the fastest ECMAscript engine on the market.

This article is originally posted on Daniel Hendrycks' Blog. Thanks for monitoring and keeping track of the speed improvements in Opera 10.50 from pre-alpha to Final version.

Was core speed tested on GOGI builds or on release builds?
