You mean that each time you hit the "DevMode On" bookmarklet and "Compile" button, it takes 4-6 minutes before the page is refreshed to reflect the changes you made in the code? (launching SuperDevMode does a "full compile" –in draftMode though, and limited to user.agent=safari & locale=default– so it's expected to take some time, but you do it only once –or a very few times– per day) Finally, you might want to setup "harnesses", i.e. small apps using only a portion of the code. That should speed up DevMode refreshes, SuperDevMode startup, and compilation; at the expense of not being your full app, so you cannot test/check everything. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Oh, and if you have to use an external device, use esata rather than usb. while usb has higher burst speeds, esata has much higher sustained transfer speeds.

Instead of compiling one permutation at a time, there is an option to compile multiple permutations at the same time by mutli-process.

Re: GWT Compilation Time Performance Improvement
Niraj: IMHO if you want to agile GWT development you want to develop using the GWT devel mode or the GWT2.5 SuperDevMode (haven't tried myself) instead modify java -> compile with ant -> see the changes. You could ignore "devel mode vs production differences" when hard - developing, and perform a main compilation only after you finished a day's work or a module and test only for those kind of differences only in production mode. Also, I would try to run the GWT devel mode using your external server application along with the rest of your webapp, instead builtin GWT server. can I know what differences are those you are talking about ?

Re: GWT Compilation Time Performance Improvement
I don't know if I am missing something, but, have you tried to upgrade to GWT 2.5 and use SuperDevMode? In my case I was needing 2 minutes each time that I made any change and now 15 seconds(or less). Maybe for your developers is worth to try it.

Re: GWT Compilation Time Performance Improvement
Maybe you should get more RAM...4GB isn't a lot when running all the things you need for GWT development. Alternatively, run some (or even all) of the required processes on another computer.

Re: GWT Compilation Time Performance Improvement
Hi Members, Thanks for all your suggestion/comments. We have already tried below mentioned options to improve the compilation time overall. 1. Memory Settings. -Xmx and Xms 2. localWorkers 3. DraftCompile The question could arise to members mind that why we need to compile a lot but the thing is :- while doing the development work If we use the development mode provided by GWT , sometimes happens that the end output in production mode is diff. then development mode. So we can not trust that what is shown in development mode will be same in production mode. Hence developers compile their code on their machine and test it before putting something on main server. The issue is developers machine have overall RAM of 4 GB only. And when Jboss , Eclipse and Compilation of GWT runs , It is very very slow. So for even the small changes , developers needs to compile , build the WAR and then deploy to check that his code is working ok or not. I am looking for some option which could allow me to pre-compile GWT modules. So that If some GWT module is not changed and when I compile the main module , that GWT module should not compile as it is not changed at all. I am not still not getting how to use the concept of "*.gwtar files" which is mentioned in our discussion. Would appreciate if someone can provide more details on the same. Thanks,Niraj.

Re: GWT Compilation Time Performance Improvement
Be happy that its only 4-6 minutes :)) You can't really speed it up because at the end the amount of source you need to compile to JS is always the same. But you can use a distributed build which could reduce the compilation time to the time of a single permutation if you have enough hosts to compile on: http://code.google.com/p/google-web-toolkit/wiki/DistributedBuilds During development you could use -draftCompile as compiler option to skip optimizations which speeds up compilation quite a bit. Do you compile that often or why does the compilation time bother you? -- J. -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT Compilation Time Performance Improvement
Niraj, you didn't mention the "-localWorkers" flag. On a quad-core machine that reduced our compile time to about 1/3 of what it was (our 300s compile time became 100s).

Re: GWT Compilation Time Performance Improvement
You could also move the compilation process to a bigger machine on the cloud and then if you need to run the compiled site locally do a script to download the content. That improved a lot the compilation time for me. You can also try doing distributed builds (I personally never tried), but here are some links: http://code.google.com/p/google-web-toolkit/wiki/DistributedBuilds http://code.google.com/p/gwt-distcc/ https://github.com/markovuksanovic/gwt-distributed-compiler On Tue, Sep 4, 2012 at 10:50 AM, Abraham Lin wrote: > What could possibly help is to precompile the modules into *.gwtar files, >> but it's something that's supposed to only be used by GWT itself (you'll >> find such gwtar files in the gwt-user.jar) AFAIK.

Granted, this is dependent on the project architecture, but it seems unlikely that this will be a silver bullet for reducing overall compilation time (at least in its current state). -- You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.

Re: GWT Compilation Time Performance Improvement
Another possibility would be to replace some classes with stubs (-> dependency injection) - only activating the functionality that is currently interesting. The rest doesn't need to be compiled. Of course it depends on the application's architecture, if this can be done easily or not.

GWT Compilation Time Performance Improvement
Hi Members, We are using GWT Version 2.4 in our current project. On server side, we are using Spring & Custom JDBC framework. We are using Maven as our Build Tool. The application is getting deployed on JBOSS 7 Server. Currently we have everything in one single Eclipse Project. Means one Application.gwt.xml file and one ApplicationContext.xml for spring. We have around 2000 Java files out of which around 1500 are for GWT related source files. The project is still growing with more source files. We are fine with timings of Java to Javac [class file] Compilation time. But when It comes to Java to JavaScript , It is a issue. We have used all hacks mentioned in the GWT Forum. Like. 1. Compiling for only one Local 2. Compiling for only one Browser But still the compilation is taking 4-6 minutes.. OR even 7 minutes some times. With this question, I would like to know the options available to improve the same. We are thinking to Split the Project like this WAY: - Module 1 (JAR Build) - Module 2 (JAR Build) - Module Main (WAR Build). This would contain Application.gwt.xml file which would inherit Module 1 & Module 2. Now Question comes: *1) Will this help us in Improving the compilation time?* *2) IF we change only Module 2 and then compile Module Main, will GWT still compile Module 1 as it is inherited by Module Main?* Please share your views on above scenario. We have even tried out GWT 2.5 option but no help in performance improvements.

Re: GWT Compilation Time
That blog post does a bunch of stuff in "step 3" that I definitely would not recommend. Building your own version of GWT for that is not necessary. You can set those properties in your own module and it will redefine them. Or if you really need to, you can just put your own UserAgent.gwt.xml in the CLASSPATH in front of the gwt libraries and that works too, you don't need to rebuild GWT for that.

Re: GWT Compilation Time
As Andrej says, there is a permutation for every "axis" you create. One for every browser, one for every locale, one for every other deferred binding axis you use. When you have 4 languages, and use the default support for 4 browsers, you get 16 permutations. To speed this up during development use only ONE locale, and ONE browser. Then when you need to test, and or deploy, roll that back. To do this use the element in your module (as opposed to just extend-property). For example: Also, make sure you give the compiler a lot of memory (the -Xmx switch to the JVM), and try to make sure you use a server VM (-server, depending on your platform and OS version you may or may not get a - server by default).

Re: GWT Compilation Time
Hi, Instead of 4 cache.html files per module (one for each browser: ff,ie,safari,opera) there will be 4 x 3(3 locales) = 12 cache.html files. It seems that compilation time depends on #permutations.

GWT Compilation Time
Hi All, I am implementing I18 support for my application and I am using GWT I18 support. In my module file, I extended three locales and compilation time for my java files increased drastically. Earlier it was taking around 30-40 mins but after adding three locales in my module configuration file it is taking around 120-130 mins. I am very surprised by seeing this much difference in compilation time. Why is it so?? Is there any mistake I made in adding support of locale to my application or something wrong with handling of I18 by GWT API?? Can anyone help me out?? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Google Web Toolkit" group.
