Summary: [META][GTK] Implement Deferred Rendering
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Unspecified
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: Layout and Rendering
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: jae.park at company100.net
This is a metabug to track Deferred Rendering in GTK+ port.
The purpose of Deferred Rendering is to perform rasterization on a dedicated thread to improve performance.
Current implementation of WebKit burdens the main thread with many jobs including layout, JavaScript execution, painting, and other heavy jobs. By performing rasterization on a separate thread, we can reduce the responsibilities of the main thread and bring a noticeable performance improvement.
For details, refer to the following design document:
