When JIT option is enabled, JS performance is much times faster than before. In Sunspider 0.9.1 benchmarks, - Disabled JIT : 1,254.9 ms +/- 1.2% - Enabled JIT : 351.0 ms +/- 2.4% Enabled JIT is 3.5 times faster than before in Sunspider benchmark. (Smaller is better in Sunspider Benchmark.) In V8 Benchmark Suite - Version 3 - Disabled JIT : 564 Richards: 429 DeltaBlue: 493 Crypto: 243 RayTrace: 1628 EarleyBoyer: 1689 RegExp 229 - Enable JIT : 3462 Richards : 3244 DeltaBlue: 3324 Crypto: 2771 RayTrace : 6077 EarleyBoyer: 4792 RegExp: 1979 Enabled JIT is 6.1 times faster than before in V8 Benchmark. (Bigger is better in V8 Benchmark.) - SUT 1. CPU : Intel(R) Core(TM) i5 CPU 750 @ 2.67GHz 2. RAM : 3GB 3. OS : Ubuntu 10.04 4. WebKit EFL Source : Clone 2011.01.10. I couldn't copy the result as text. So, I capture the screenshots. Please find attachments. When I turn JIT on before, EWebLauncher comes to crash. However, recently, even though JIT is turned on, EWebLauncher doesn't come to crash. WebKit EFL Guys, How do you think about turning JIT on ?
