I migrated a project from GWT 1.5 to 1.6 with extreme slowness in
hosted mode - compiling and running in web mode performed the same
with no performance hits.
I was using the GXT and  gwt-google-maps modules.

I went from 5 second to over 60 seconds to do a simple refresh in
hosted mode. It has nothing to do with hardware as hosted mode ran
idle for over 40 seconds doing nothing before even the smallest bleep
on my Quad core.

When I moved all files within the <module>/public directory out into
the war project directory structure, I got hosted mode to at least
preform approx. the same as GWT 1.5. At a minimum my hardware
resources are actually being used now when I refresh the hosted mode
browser. I never had any explanation why a seemingly simple static
file copy for  ~1MB of static files hung hosted mode for 40 seconds.

If you have anything in any <module>/public directory I would move it.
