In case that it is important:
I'm using local Tomcat 7 started from inside Eclipse Luna SR2 Win 8.1.
My application in Tomcat is deployed, I open it in the browser and click the code server bookmarklet then.

Best regards
Blama

Retested with BuiltInDS - similar numbers

Hi Isomorphic,

I tried the same for the BuiltinDS sample and the result is the same. Also the numbers are so close that it is clear that most of the time is spent with either static resources or unchanged SmartGWT code.

Please see the logs. Perhaps it is easier for you to disregard the previous logs, as this now was done with BuiltInDS (with com.smartgwtee.SmartGwtEENoScript and loading your js-scripts in BuiltInDS.html):

Please see how the number "4872 units" is similar to the "5049 units" from my application in the original post. If that means that I have about 180 classes I think that this is about right. This also means that huge amounts of time are spent compiling SmartGWT resources that don't change as long as I don't change the nightly in use.

Here you can also see the many GET /progress after "Linking Public artifacts", which shows that here many time is taken - the compile of the changes was just milliseconds.

My two questions are:

Is the linking step normal and can I do something to make this shorter? (I asked this one in the original post as well. The OP includes details on what static resources are processed here)
Most likely you saw the 2015's GWT.create incremental-compilation talk (especially 9:45-12:00).
If I understand correctly linking has to take longer today than it could in the best case, but I don't know if that means we really need all the static resources or if it only means that we have to create and transfer the whole <safename>.cache.js file (300kb in case of BuiltInDS).

The codeserver startup begins always with

Code:

Persistent unit cache dir set to: C:\Users\myuser\workspace\lib\smartgwtpower-5.0p\samples\built-in-ds\codeserver\com.smartgwt.sample.BuiltInDS\compile-1\gwt-unitCache
   Looking for previously cached Compilation Units in C:\Users\myuser\workspace\lib\smartgwtpower-5.0p\samples\built-in-ds\codeserver\com.smartgwt.sample.BuiltInDS\compile-1\gwt-unitCache
   Found 0 cached/archived units.  Used 0 / 4872 units from cache.

      100% complete (ETR: 0 seconds)
      Compilation completed in 219,33 seconds
   Added 4872 units to cache since last cleanup.

It seems that it does not reuse the work done in the last run ("Found 0 cached/archived units. Used 0 / 4872 units from cache."). Is there a way reuse the contents of "compile-1\gwt-unitCache", resulting in a faster or almost-no-time startup? I did not find anything related to this using google. While I realize that this question is more related to GWT than SmartGWT I'm pretty sure you noticed this as well and perhaps have a solution.

Hi Isomorphic,

out of curiosity I tried this change to BuiltInDS.gwt.xml:

Code:

<inherits name="com.smartgwtee.SmartGwtEENoScriptNoTheme" />
<inherits name="com.smartclient.theme.enterprise.EnterpriseResources" />

because I thought perhaps I can get rid of the other skins this way (see the block with -logLevel DEBUG in the 1st post, there are files for Graphite, ToolSkin and ToolSkinNative).
But doing so there are no changes in the amount of time needed for either 1st compile or recompile after string change.

Best regards
Blama

**Isomorphic** · 20 May 2015, 06:39

We don't see any unexpected behavior when testing the official 5.0p SDK, using the two overridden files you provided, and Chrome 42:

- The initial processing upon launch of the CodeServer took 73.8 seconds.
- The first compile triggered from the browser took 12.9 seconds.
- A recompile triggered with no Java source change took just 0.07 seconds.
- A recompile triggered with a simple string constant change or a new local variable took 2.8 seconds.

These numbers depend on the specific PC of course (the machine above is a Sandy Bridge 3.9GHz desktop), but the important point is the ratio of first triggered compile time to the next (incremental) compile (triggered from the browser), which is 22% in this case for a simple change.

The Eclipse project used to test this included GWT SDK 2.7.0 and all of the libraries in the SDK's lib directory in its build path, and used linked folders (pointing at the dirs in the SDK) for the src and war directory of the Eclipse project.

It doesn't immediately look like there's anything here for Isomorphic to address. Any additional optimization would appear to be in GWT's court.

Note that:
- From this thread: https://groups.google.com/a/gwtproje...ws/rynZVZFyPHY it appears that for GWT 2.7.0 you may need to use the Chrome browser for caching to work.
- A user has filed a bug similar to what you are reporting here: https://groups.google.com/forum/#!ms...0/Odc0If8LeRcJ against GWT, so that also would indicate it's not a SGWT issue. One comment mentions a fix might be in the next SDK release (2.8?)

**Blama** · 20 May 2015, 07:17

Hi Isomorphic,

thanks for testing. I will retry with Chrome as well.
I'm using i7-3632QM (Ivy Bridge, 2,2 GHz) with SDD Samsung 840 Pro. Assuming you use a SSD as well this configuration should be a bit slower than your setup, but not much.

What do you mean by "used linked folders"?
Can you provide the "Program arguments" from the "Java Application" in the Eclipse Debug configuration mask?
Mine is (using Java like in your SDM-Setup guide):

Code:

-src src -workDir ${workspace_loc:builtinds}/codeserver -port 1234 com.smartgwt.sample.BuiltInDS -logLevel TRACE -war C:\Users\myuser\workspace\lib\smartgwtpower-5.0p\samples\built-in-ds\war -incremental -precompile -workDir C:\Users\myuser\workspace\lib\smartgwtpower-5.0p\samples\built-in-ds\codeserver

The folder is not my Tomcat webapps folder. Do you have your Tomcat webapp folder there? Perhaps that saves the linking step some time, although I do not know how that should be possible.

Do you see the static resources as well when using -logLevel DEBUG? If so, then it is a speed problem of my PC - although it still would be a waste of time, even on your system.

Best regards
Blama

**Blama** · 20 May 2015, 07:29

Hi Isomorphic,

I forgot. The question in the GWT group (your last link) is from me. The "Restart SDM" issue is of course GWT only (as I wrote under the question) and would be a nice speedup (from GWT).

I'm more concerned with the way more often happening steps

Code:

- A recompile triggered with no Java source change took just 0.07 seconds.
- A recompile triggered with a simple string constant change or a new local variable took 2.8 seconds.

In my "Change of one String and recompile"-logs you can see that the compilation took 3,837s and the total time is 36,245s.
This 3,837s is near your 2.8 seconds and in the expected range with regards to your more powerful system. I'm worried about the time after that, from second 4 to 36.
Perhaps this is linked to your "linked folders" (if it is not a command line option for the codeserver, could you explain what it is?).

Thank you
Blama

**Isomorphic** · 20 May 2015, 08:11

The command line arguments to CodeServer were:

Code:

-src /home/iscdev/Downloads/smartgwtee-5.0p/samples/built-in-ds/src -logLevel TRACE com.smartgwt.sample.BuiltInDS

By linked directories, we mean that the src and war folders in the Project were not inside the Eclipse workspace, but references to external dirs. (You would configure this by right-clicking on the project tree, etc.) Eclipse indicates this by labeling each a "Linked Folder" - check the Eclipse docs. If you look at the .project file itself, they'll appear like:

Code:

<linkedResources>
    <link>
        <name>src</name>
        <type>2</type>
        <location>/home/iscdev/Downloads/smartgwtee-5.0p/samples/built-in-ds/src</location>
    </link>
    <link>
        <name>war</name>
        <type>2</type>
        <location>/home/iscdev/Downloads/smartgwtee-5.0p/samples/built-in-ds/war</location>
    </link>
</linkedResources>

The 2.9 seconds I gave is the total time:

Code:

          :

Hi Isomorphic,

unfortunately I could not solve my long-linking problem, yet.

But I made two interesting discoveries.

When you use the Eclipse GWT plugin to start SuperDevMode, the reuse of the already compiled JS-files seems to work, resulting in a faster codeserver-start. See these logs:

Code:

This does even work if you change a java file while the codeserver is down. On start it then just compiles the changed file. See this startup log excerpt (the end shows it effect) for a changed String:

Using Eclipse GWT plugin it is no longer needed in the browser to use the bookmarklets and to manually hit compile. Java-file change, Ctrl-S save in Eclipse and F5 Reload in FF26/GC42/IE11 are enough to trigger the recompile (funny thing though: The same <safename>.cache.js is created and delivered for FF26 and IE11 (binding: user.agent=gecko1_8 in the logs for both, this might be a GWT bug)).

I think this is good news with the caching and the auto-recompile on refresh.

Back to the long-linking problem:
I'm still not sure that your PC is not just way faster with the linking step. Under Windows filesystem operations are way slower than under Linux (and most likely also way slower than under MacOS).
Your path suggested that you might not be using Windows (or Eclipse uses its own format). Could you start SuperDevMode like before, but with "-logLevel DEBUG" (sorry, I said TRACE before, but only debug shows the "Emitting resource xyz" messages).
If you get the messages and are that fast anyway I have a problem with my system. If not, I'll have to search further.

Thank you & Best regards
Blama

Can you be more specific about what type of run configuration you're using? In our docs, we describe using a Java Application RC to start the Code Server, and a Web Application RC to deploy production mode (if not already achieved through other means).

If you're referring to all the messages about copied resources, yes, we get them even for the quick (3 second) run for incremental changes. For example, a snippet is:

The PC used to get the test numbers presented earlier indeed is running Linux, but it's hard to believe the file system difference between ext4 and NTFS would be that significant. Although it does have a 7200 rpm drive, it has the non-default option "strictatime" applied to that volume (for debugging) which would tend to slow it down.

Hi Isomorphic

Can you be more specific about what type of run configuration you're using? In our docs, we describe using a Java Application RC to start the Code Server, and a Web Application RC to deploy production mode (if not already achieved through other means).

You have this in your SuperDevModeTroubleshooting-docs:

Deploying your Web Application
You should now launch the "Web Application" Run Configuration that it was suggested you use - the simplest way is to Right Click on the Project / Run As / Web Application. Visit the URL generated by Eclipse, without the gwt.codesvr parameter. You may see a warning about needing a recompile - you can either ignore this or run a full compile once to get rid of it. (If you've deployed your Web Application manually outside of Eclipse, this section can be skipped.)

This applies to me, I'm using local Tomcat as Webserver, because I use your JDBCRealm setup + declarative security.

I was talking about SDM Codeserver start you do with "Java Application" Run Configuration.

When I switched this to "Web Application" Run Configuration I got the benefits I mentioned. See the screenshots of the Run Configuration window.
My argument line is:

-noserver -superDevMode -codeServerPort 9997 -remoteUI "${gwt_remote_ui_server_port}:${unique_id}" -logLevel TRACE -workDir "${workspace_loc:builtinds}/codeserver" -startupUrl http://localhost:8080/builtinds/BuiltInDS.html -war "C:\Program Files\Apache Software Foundation\Tomcat 7.0\webapps\BuiltInDS" com.smartgwt.sample.BuiltInDS

Please note that I just dropped in GWT 2.7.0 and changed all environment variables to point to it - as it seems the Google Plugin for Eclipse 4.4 does not provide newer version with GWT 2.7.0, yet.
Please also note that with the current version of the Plugin you'd need only one Eclipse Run Configuration also if you do not use an external Tomcat. On the GWT tab you can start the Jetty server as well.

The linker problem:

If you're referring to all the messages about copied resources, yes, we get them even for the quick (3 second) run for incremental changes.

Yes, I was. Thanks for verifying.

I'm wondering myself. But you know the crazy directory delete times with Windows...so I would not take it for granted that it is impossible. Another idea: I'll run with disabled antivirus again. Perhaps this also costs performance.
Could you try with a similar powered Windows PC as well? I'd test myself with Linux, but I don't have a system here (small startup company).

Using Windows 7 SP1 x64 on the same hardware I do see somewhat higher numbers:
- 84 seconds for the initial run
- 5.4 seconds for the recompile after an incremental change

Perhaps it is NTFS, or Java might be less efficient on Windows. In any event, I don't believe there's an issue with SGWT.

We'll review what you mentioned about using the GWT Web Application to run the CodeServer and may update the docs.

Hi Isomorphic,

I agree. It does look like it is my system. But it is five times slower than yours. A difference this big can't possibly be caused by the hardware, so I have to analyse more.
My virus scanner is on-demand and not always-on, so this can't be the source, either.
What Java version are you using? I'm still on Java 7. Under Linux, do you use Oracle JDK or Open JDK?

Even if it does not seem necessary: Do you have an easy way of stopping the generation of these public artifacts - it seems that the generation is useless (only static files that are already available), even if it does not take much time for you.

Best regards
Blama

For the test numbers, Oracle JDK 8 was used in Eclipse.

It's unlikely this will happen as a high priority task, but we may review the situation when we get a chance to see whether any simple changes can be made to avoid that - but it may require a fix from GWT.

Ok. I'll switch then and retest. I have to do that anyway.

Ok, I understand.
