We're working on making it faster. If you'd like to find out where it's spending its time (and perhaps provide us another useful data point): update to trunk and add -Dgwt.speedtracerlog="/path/to/myproject-speedtracer.html" to your JVM arguments. Launch your app, maybe do a refresh or two. Install the Speed Tracer Chrome Extensio<https://chrome.google.com/extensions/detail/ognampngfcbddbfemdapefohjiobgbdl>n (and give it access to local file URIs in chrome://extensions). Open the resulting trace file in chrome, click "Open Monitor" and check out the visualization. You'll want to expand the initial timeline view. The most interesting data is going to be the summary pie chart you get from clicking on the Module Init row. Feel free to share screenshots of those summary pie charts in this thread.
