Summary: Massive performance problem with typed array
constructors
Product: WebKit
Version: 528+ (Nightly build)
Platform: Unspecified
OS/Version: Mac OS X 10.8
Status: UNCONFIRMED
Severity: Normal
Priority: P2
Component: JavaScriptCore
AssignedTo: webkit-unassigned at lists.webkit.org
ReportedBy: evan.exe at gmail.com
The attached page uses binary search to find the maximum size that the Uint8Array constructor accepts. In Firefox and Chrome the test completes in 4 seconds but with both Safari and WebKit Nightly the test takes 15 minutes and eats up 40gb of virtual memory. This is on a MacBook Air with 4gb of memory.
