Greetings, As you know the WebKit project has a very complex memory manager that cannot be swapped easily but The Qt Project might be interested for a faster alternative than the garbage collector: http://lists.qt-project.org/pipermail/development/2016-December/028199.html This is just a head's up in case anybody is interested into the subject and is aware of Qt. I know by experience garbage collectors will always let you down for complex projects so I think there is no other solution. Thanks & Merry Christmas, -Phil
