Hi guys, I too have been stung by these performance issues and, although things are not yet as good as they can be, I found the following helpful:
Make sure localhost is defined in your /etc/hosts file. More info here: http://groups.google.com/group/google-web-toolkit-contributors/browse_thread/thread/66c716540cdb7a77/c528d86df893ff96#c528d86df893ff96 I'm actually on Windows 7 and it turns out that the default behaviour now is to leave the definition of localhost to DNS. For me, adding an explicit definition of localhost to C:\Windows\System32\drivers\etc \hosts improved things (at least I think so - or maybe it's my perception?!). Also, if you're using Chrome then the dev channel has recently been updated to version 4.0.266.0 (check this via "About Google Chrome" on the tools menu). Upgrading to the latest version also made a positive difference. Finally, you may be able to change your app to help performance. Obviously this will not be a realistic option for many, but I found that the CPU cycles are burned processing my app code, albeit rather inefficiently at this stage. Nonetheless, the slow performance is a massive exaggeration of my app performance. A quick scout through my code revealed several opportunities for introducing lazy initialisation and eliminating some third party libraries, so making some changes to my app also made a big difference to the speed of development. As I said, still not ideal, but I hope these issues will be resolved soon. Cheers, Chris.
