I'm using Eclipse Galileo with latest GWT 2.0 version in development mode, but it runs really slow (I need to wait about a minute to open one page, but after compilation, my application works very well when I run it using Tomcat 5.5).
My code is not too heavy and I guess there is an OS-related or software inconsistency problem, because I'd this problem before, but when I reinstalled Windows Vista SP2 (I formatted my Windows drive and reinstalled it), my problem was resolved for a few days and then again it became too slow.
I didn't install any special software on my Windows machine, so I really don't know why this problem occurs. Any suggestion ?
Delete gwt cache from temporary folders like images. rpc files..etc. than see the performance. it is one of the cause to slow in hosted mode.
