Bug ID: 173051
Summary: Poor performance with asm.js
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: JavaScriptCore
Assignee: webkit-unassigned at lists.webkit.org
Reporter: ashley at scirra.com
Safari doesn't support any open codecs so we're using an asm.js compile of ffmpeg to decode Opus audio here: https://www.scirra.com/labs/audiotest/
The page is very slow to load on an iPad Air 2, despite not processing much data. It only decodes 23 files totalling ~750kb of compressed data. However this considerably slows down loading times for web content that uses this approach.
