Any plans to write a native GWT Compiler like jikes for java? I know
there are plans to improve GWT compiler performance in the upcoming
1.6 release of GWT by multi-threading but I am not sure that will make
enough difference. A native compiler like jikes would be better and
much faster.
Our product, JobServer (job scheduling engine) uses GWT for its GUI
SDK and we compile GWT components on the fly the first time the GWT is
used. This frees the developer from doing the GWT compiler if they do
not want to. This works very well but the initial GWT compiling of the
GWT UI components can take minutes sometimes and is annoying. I would
really like this to be more like compiling JSP pages for example.
Anyway I can only hope that GWT compiling gets faster (right now it is
getting slower with all the advanced optimizations done in GWT 1.5 :)

Hi Rauf,
There are currently no plans to rewrite the GWT compiler as a native compiler. There are plans to speedup compilation time with the current GWT compiler, however, and the team is in the know about long compilation times that some developers have been experiencing when moving their projects form 1.4.x to 1.5.
The new multi-threaded compiler is available in trunk if you're interested in checking it out to see if it helps speed up your application compile time.
From benchmarks we've run and what some developers have been reporting, the new multi-threaded compilation has been showing significant improvements in compilation speed, so you should be getting faster results for your own project as well.
Hope that helps,
-Sumit Chandel

Hi Sumit,
This multithreaded compiler sounds intriguing. Could you provide some
guidance about how to get it and use it?
Thanks,
Alex

get it : "The new multi-threaded compiler is available in trunk if
you're interested"
use it : like the google web toolkit .

I interpreted "available in trunk" to mean that it's a separate
version of the compiler in the trunk. Has it replaced the single-
threaded compiler and can just be built and used as usual?

I checked out the trunk and I'm running the compiler from it, but I'm
not seeing any performance boost and only one CPU core is being used.
Is there a command-line switch to turn on multiple threads?

Does anyone know the answer to this question asked by Dobes:

myself - I didn't believe it would actually be enabled by default.

That's why I was reluctant spending at least an hour trying this

Hi Alex, Dobes,
There is a flag that you need to pass in to have the compiler run in multi-threaded mode.
The flag is:
-localWorkers N, where N is some number greater than 1, depending on how many threads you want to use to compile your GWT application. Sorry for not mentioning this earlier.
Hope that helps,
-Sumit Chandel

Thanks, Sumit. Can this arg also be used for GWTShell?
