Re: What is the minimum Internet speed connexion that the GWT team is considering when testing their GWT application ?
I do not see the difference (can you indicate me a piece of code) between
*ClientBundle with CssResource *and *ClientBundle + CssResource *?
There is no difference, I just was a bit lazy to write with again ;-)
*#2*
*
*
You have to create a separate ClientBundle/CssResource that you only
use inside your admin area.
I have :
* public interface AR extends ClientBundle {*
* public static final AR ADMIN_RES_INSTANCE =
GWT.create(AR.class);*
*
*
* public interface Acss extends CssResource {}*
*
*
*
@Source(A.css)
Acss adminCss();
*
*}*
(NB: AR = AdminResource, Acss = AdminCss):
My question is : Should I call *adminCss().ensureInjected()* AFTER the
split point ? Actually, I call ensuredInjected() in the MananaSeguro#*
EntryPoint*() of my application.
You have to call it inside the split point, e.g.
GWT.runAsync(new AsyncCallbackAdminArea() {
onSuccess(AdminArea adminArea) {
AR ar = GWT.create(AR.class); //could also be called inside AdminArea
ar.adminCss().ensureInjected(); //could also be called inside AdminArea
app.show(adminArea);
}
});
If you want a clean split point you have to reference the code you want to
split out the first time inside the onSuccess() method and nowhere else.
Your static INSTANCE variable would prevent your ClientBundle to be
downloaded in the split point because this will create an instance during
app startup and to create it GWT has to know the code.
*#3*
My last question (I hope...), is that I have not succeed to use GWT 2.5
SUPER DEV MODE. The doc talks about a -- * Dev Mode On bookmarklet* -- (
https://developers.google.com/web-toolkit/articles/superdevmode) but this
bookmarklet never appear in my case. What should I missed ?
You have to visit the Super Dev Mode code server on http://localhost:9876
and drag and drop the bookmarklet into your browser's bookmark bar.

Re: What is the minimum Internet speed connexion that the GWT team is considering when testing their GWT application ?
Hello, Ok, firstly I should read the documentation, and I will do it, but maybe you could clarify me most of my preoccupations : For now it seems that my resources (images, css) are taking enough memory at the initial download. Maybe you can help me to reduce it... :) I am asking the following : *#1* I have not used *inline CSS*, I mean, I did not put any css code in my *ui binder* files. I just use 3 stylesheets (admin.css, common.css, normal.css) that are declarated in the client bundle. - Will *inline css *reduce the code to download ? - How could I do to not download the admin.css at startup but just when the user go to the admin ? *#2* Actually I am thinking that : all images declarated as ImageResource or DataResources inside a ClientBundle will be download at startup time. Is it true ? *#3* As Joseph tolds me, the server should compress the content (RPC + images) ? - Could I do that with *YUI **Compressor** *? - I heard about a tool to compress images (Webp - https://developers.google.com/speed/webp/index )...Should I use a combination of YUI Compressor AND Webp ? - How to compress RPC ? *#4* Finally there is so much tools that I do not what should be the *code optimization workflow* ? ** I assume that I should not go to a further step without having accomplished the current one. (I would not play with speed tracer without having already analyzed all code split points) For the moment, my vision about using tools for code optimization is the following one (could you correct or complete me if I have misunderstood or have forgotten an important thing ?) : *step 1* - (compiler) - Use -compileReport and see where should I introduce *code split points*. *step 2* - (plugin) - Use *inspectorwidget *(I have not used yet...) to optimize the DOM structure (minimizing the use of gwt widgets). *step 3* - (tool) - Use *Speed tracer* to see what happen at execution time (if handlers are slowing my app) *step 4 *- (tool) - Use various other tools to see their suggestions about optimizing the code: -* Page speed Service* : https://developers.google.com/speed/pagespeed/service) - *WebPageTest* : http://www.webpagetest.org/ - *YSlow *: http://developer.yahoo.com/yslow/ *step 5* - (compiler) - when ready for production, use more compiler option (closureCompiler...) to reduce the javascript code generated. Remarks, I do not know at witch moment should I use* Chrome Developper tool*with the Timeline, Profile ... functionalities ?

Sorry, that was confusion. Using CSS directly in the *style* attribute is an anti-pattern. What I meant was that if you use the CssResourcehttp://code.google.com/p/google-web-toolkit/wiki/CssResourceCookbookinterfaces, then GWT will combine and minify your CSS automatically for the smallest possible package. This is great since if you point the Chrome audit tool at most sites, they will show that they have downloaded 3000+ unused styles. Further, only these are inlined into your JS file by the compiler (what I was referring to), then you no longer need to download any CSS files at load. *#3 *As Joseph tolds me, the server should compress the content (RPC + images) ? - Could I do that with *YUI **Compressor** *? - I heard about a tool to compress images - I heard about a tool to compress images (Webp - https://developers.google.com/speed/webp/index )...Should I use a combination of YUI Compressor AND Webp ? - How to compress RPC ? I was not referring to the YUI compressor. The compiler in GWT (and the Closure Compiler in 2.5) do a far better job than the minimizer that is YUI Compressor. I meant you should enable gzipping of compressible resources (not images). This depends on your server. I'm running Apache, so I just use mod_gzip. There are many tutorialshttp://www.techiepark.com/tutorials/how-to-enable-gzip-compression-in-apache-server-to-speed-up-website/out there. As long as the sender accepts gzip encoding, you'll be fine.

*#1* I have not used *inline CSS*, I mean, I did not put any css code in my *ui binder* files. I just use 3 stylesheets (admin.css, common.css, normal.css) that are declarated in the client bundle. - Will *inline css *reduce the code to download ? If you use ClientBundle with CssResource your CSS code is already inlined into your app. Inlining itself does not reduce the download size, but if you use ClientBundle + CssResource GWT will minify your CSS. That means it removes unused CSS classes, converts your possibly long CSS classnames into shorter ones, merges CSS classes and rules where it makes sense and removes all white spaces. So I would say you can't make it any smaller. The only thing you can do is to tell GWT to shorten your class names even more. - How could I do to not download the admin.css at startup but just when the user go to the admin ? You have to create a separate ClientBundle/CssResource that you only use inside your admin area. Then you use GWT's code splitting and you split out your admin area. If done correctly your app will start/load without any code from your admin area and once you click on admin and you pass your code split point GWT will load the admin code (which includes the admin ClientBundle). *#2* Actually I am thinking that : all images declarated as ImageResource or DataResources inside a ClientBundle will be download at startup time. Is it true ? Not 100%. For IE6 and IE7 GWT will create a combined image that contains your small images. That means if you have 4 icons with 16x16 pixel size then GWT will create a single 32x32 pixel image that contains these 4 icons and GWT stores information about where to find these 4 icons in that combined image into your app. Obviously this won't work for animated gif's. This does not reduce the download size of the images itself, but it saves some network overhead (less server requests). These combined images won't be loaded at startup time, they will be loaded when you need them. For other browsers GWT only inlines Images if they are not too large. If you disable image inlining globally then GWT will use combined images for every browser. *#3* As Joseph tolds me, the server should compress the content (RPC + images) ? - Could I do that with *YUI **Compressor** *? - I heard about a tool to compress images (Webp - https://developers.google.com/speed/webp/index )...Should I use a combination of YUI Compressor AND Webp ? - How to compress RPC ? As Joseph already said, the best compression you can get is to configure your web server to use gzip compression. And if you don't want your web server to compress your resources on the fly then you could also use GWTs Precompress linker (http://code.google.com/p/google-web-toolkit/wiki/PrecompressLinker) that will generated gzipped files for you. Most web servers can be configured to serve these gzipped files. *#4* Finally there is so much tools that I do not what should be the *code optimization workflow* ? First I would think about GWTs split points. They can really save you a lot of startup time. For example we have a 3 MB permutation but only have to download ~800kb at the start of the app because of split points. In combination with gzip compression on the web server these ~800kb will become ~300kb that a user has to download...thats 10% of the permutation size. The rest of the code will be loaded when needed. So these two points will save you the most! And of course it helps if: - you can reduce the amount of different GWT widgets used in your app - simplify the DOM if possible - you don't have duplicate/similar code lying around (try Googles CodePro Analytix for Eclipse to find similar code and refactor it) *BUT* these optimizations are really time consuming and won't give you such a great benefit in terms of size reduction. So I would not give them a high priority (well ok, except duplicate/similar code refactor ;-)). -- J. -- You received this message because you are subscribed to the Google Groups Google Web Toolkit group.

What is the minimum Internet speed connexion that the GWT team is considering when testing their GWT application ?
Hello, I am living in Bolivia and here, I have a connection equals to 200 Kbps (it is very poor). :( So I was asking if google engineers are considerating a minimum bandwith when testing their app ?

In other terms, does '*Google*' recommend a minimum Internet connexion to use a GWT application in production ?

I'm not sure it's possible to make a general statement; it depends on your application. If you haven't already done this, take a look at -compileReport; it can show you what contributes to the size of your application. https://developers.google.com/web-toolkit/doc/latest/DevGuideCompileReport Also try adding these options to reduce the size of your generated application: -XdisableClassMetadata (breaks getClass().getName()). -XdisableCastChecking (eliminates ClassCastException). https://developers.google.com/web-toolkit/doc/latest/DevGuideCompilingAndDebugging#DevGuideCompilerOptions On Jul 3, 5:03 am, regnoult axel regno...@gmail.com wrote: Hello, I am living in Bolivia and here, I have a connection equals to 200 Kbps (it is very poor). :( So I was asking if google engineers are considerating a minimum bandwith when testing their app ?

Re: What is the minimum Internet speed connexion that the GWT team is considering when testing their GWT application ?
Also make sure the server is compressing content, both for static resources and for your RPC calls. That will help with the initial download a lot too. Also consider using the ClientBundle resources like CssResource and ImageResource. If your internet connection is so poor, I think you're better off inlining some of those small images and CSS rules, rather than making additional requests. Best luck.

FWIW, I'm using these optimization options in my *.gwt.xml file: !-- Obfuscate RPC class names (shrinks large string literals) -- inherits name='com.google.gwt.user.RemoteServiceObfuscateTypeNames'/ !-- Strip out stack trace code to reduce JavaScript size -- set-property name=compiler.stackMode value=strip/ !-- This option assumes that we don't access enum string names -- set-configuration-property name=compiler.enum.obfuscate.names value=true/ Each of those options reduces the size of the generated JavaScript; the extent of the improvement will depend on your particular mix of code.

Also, I'm assuming you're generating Obfuscated code for production; the other formats are readable for debugging, but they're about 10x bigger. If you drill down into the lower levels of those reports, they provide more detail about individual components. You can find some articles about optimizing GWT here: https://developers.google.com/web-toolkit/doc/latest/DevGuideOptimizing One more suggestion: Add this to your *.gwt.xml file: set-property name=compiler.stackMode value=strip/ It's explained here: http://code.google.com/p/google-web-toolkit/wiki/WebModeExceptions#Co...

Re: What is the minimum Internet speed connexion that the GWT team is considering when testing their GWT application ?
well, it *has* to be downloaded before it can be executed, there is no way around it. you can try to split your code into smaller parts (google: code splitting gwt) so you don't get over much more than your 17 seconds. Am 03.07.2012 14:03, schrieb regnoult axel: Hello, I am living in Bolivia and here, I have a connection equals to 200 Kbps (it is very poor). :( So I was asking if google engineers are considerating a minimum bandwith when testing their app ? This is important, because when starting my aplication (www.mananaseguro.com) , even if I am trying to optimize it, I have for the moment 17 seconds to wait to see the first page (and my app is minimalist) for*the first time*. Then I think it is due to the cache, it loads a lot faster (4 seconds, such as when I open GMAIL here). In other terms, does '/Google/' recommend a minimum Internet connexion to use a GWT application in production ? Could you give me indications or details explaining why the first time loading is a lot slower and then why it loads quickly (I think it is because informations are stocked in the browser cache, but what kind of information exactly ?)
