Comment by key...@gmail.com: I am experiencing really slow times (30-40 seconds) when I refresh the page on safari or firefox. It almost seems to recompile the full app every single time I hit refresh. I don't even change anything, and this the app you get when you create new Web App in eclipse. Meanwhile the browser hangs like it's supposed to when making a synchronous server request.
Specs: Eclipse 3.5, Mac OS 10.6, Java 6 64-bit (tried with 32-bit 5 and 6), GWT 2.0 RC2 and GPE 1.2 RC2 (tried RC1 for both of those too. For more information: http://code.google.com/p/google-web-toolkit/wiki/GWT_2_0_RC -- http://groups.google.com/group/Google-Web-Toolkit-Contributors
