Big job, talend slow ...

Hi,
I´m creating a job that have:
- 29 tFireBirdInput,
- 01 tFireBirdOutPut,
- 08 tOracleInput,
- 01 tJavaRun,
- 01 tMap components.
I have a notebook with 1.66ghz duo core, 1gb RAM, java 1.6.0 and for this job talend become very very slow. Sometime when i try to save my project a message appears: "Error: Save java heap". Generally i need to close my talend session and open it again.
Sometimes when i click on "run job", appears some windows asking me if i wanna close the workbench or not.
I´m using talend 2.1.0M2. Talend 2.1.0.M1 have the same problems.
Anybody know something about it ? Its because are a MileStone ?

Re: Big job, talend slow ...

From what I can tell, it would be more java related than Talend related. I had the same problem on some occasion and its because my job address way too much memory and takes too much resources.
it may be related to Talend if the way they handle some things are not memory efficient but seeing your job components, I think it's just too big a job!

To launch Talend Open Studio with more memory, try to create a .bat or .sh whith the following command.
Your laptop have got 1 GB, you should use
TalendOpenStudio -vmargs -Xms512m -Xmx512m -XX:PermSize=128m -XX:MaxPermSize=128m

On Windows, you can also set arguments directly in the link property, add at end of "Target" field (file path of Talend) the vm arguments such as :
\TalendOpenStudio.exe -vmargs -Xms512m -Xmx512m -XXSmiley TongueermSize=128m -XX:MaxPermSize=128m

From version 2.1.0RC1 you can tune the memory allocation for your JVM, please have a look at http://talendforge.org/wiki/doku.php?id=doc:installation_guide
