Opera 10.50 Beta Out, With Competitive JavaScript
Opera has released its 10.5 beta (for Windows only; Linux and Mac coming). Opera calls 10.5 "the fastest browser on earth," but the jury is out on this claim. WebMonkey says that the new beta feels snappy in their informal testing. Both CNET and ZDNet ran two quick benchmarks that measure JavaScript performance, SunSpider and V8. ZDNet found Opera beating out Chrome in SunSpider but lagging in V8. CNET found Chrome ahead in both tests. What is clear however is that Opera's Carakan JavaScript engine has made up much of the ground in the performance wars; The Reg estimates that 10.5 is seven times faster in the JavaScript stakes than Opera's shipping 10.1 release.
They quite clearly explained that this was because the Linux and Mac versions were undergoing much bigger changes than the Windows version. And they will be faster and better integrated as a result. How is that a "fail"?
Clever signature text goes here.
roman_mir, It would have been clearer if you referred to it as base 64 *encoding*, rathern than encryption, since it has nothing to do with cryptography.
On an unrealted note, with regards to the V8 performance test, the reason Chrome's V8 engine works well with the V8 benchmark is because the tests themselves are bias towards the specific optimisations that the Chrome developers have chosen to include in their V8 engine.
Carakan, on the the other hand, has, for various reasons, been developed to optimise for different cases. There are trade-offs here which, as a result, affect the performance of Carakan in some of the tests included in the V8 performance test.
Disclaimer: I work for Opera the on Carakan team. I cannot go into specifics about what optimisations and trade-offs have been made.
