Yeah, you fixed the redeploy - works great now (in fact AS5 is approaching AS 4.2 speeds on my machine for startup and deployment :-). I think Shane and you/Marko got your wires crossed, and his latter comments are regarding runtime not deployment performance. From: anonymous wrote : It does get called a lot from javax.faces.application.ViewHandler.renderView() - there are 524 invocations of org.jboss.virtual.plugins.vfs.VirtualFileURLConnection.getInputStream(). Shane is talking about runtime performance (when rendering a view) NOT about deployment :-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4184649#...
