Yes, I do. I just found your post searching for "devmode performance". I wish I knew how to fix it as it makes development painful. I'm also on a Mac - a new Macbook Pro with 4GB RAM, and it just gets hosed by GWT development. As you say, the dreaded rainbow wheel of death is everywhere. Eclipse or IntelliJ starts taking a second to respond to respond to keystrokes. It's odd because activity monitor (inexact science, I admit) shows low CPU use, and a GB of inactive memory, so what else could it be... disk IO, message passing? -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
