This is a perquisite to experiment #4 \"Titanium apps are slow because JavaScript is slow and ASM JS will make them run faster\" and experiment #8 \"The deployed JavaScript engines are slow and should be upgraded\". See this page for the list of experiments :https://wiki.appcelerator.org/display/spe/Platform+Performance+Improvements\r\n\r\nThe Titanium JavaScript benchmark should not run on Titanium initially. Instead it should be a native app on each platform that exercises Titanium JavaScript use cases. The allows a rapid iteration on measuring Titanium use cases without requiring a port of the Kroll layer to each engine on each platform. A separate effort to identify these Titanium JavaScript use cases is requried.\r\n\r\nThree engines should initially be included: JavaScriptCore, V8 and SpiderMonkey. The Code Processor was identified as a fourth engine possibility. It was roughly estimated that the Code Processor could be self-hosted in 4 weeks, so this it should be included in longer range plans.\r\n", "attachment": [], "flagged": false, "summary": "Create JavaScript benchmark suite specific to Titanium use cases", "creator": { "name": "mlangston", "key": "mlangston", "displayName": "Matt Langston", "active": true, "timeZone": "America/Los_Angeles" }, "subtasks": [], "reporter": { "name": "mlangston", "key": "mlangston", "displayName": "Matt Langston", "active": true, "timeZone": "America/Los_Angeles" }, "environment": null, "comment": { "comments": [], "maxResults": 0, "total": 0, "startAt": 0 } } }
