Talend community forum / TOS more and more slow

fsoyer · 2007-03-19 17:48:35

Hi staff,

I have a problem with TOS 2.0 (M1 or M2 same problem) : it is increasingly slow progressively with launchings. And finally, it become unusable (many minutes to just save a job !) and finish with a "java heap error". If I quit and restart TOS, it's better, but at a time I must restart Windows because it is nevertheless slow.

I'm on XPPro, TOS 2.0.0M2, JRE 1.5.0.110 , ActivePerl 5.8.8 b820; Athlon XP 1.5 Ghk, 512 Mo.

An idea ? JRE version ? Which version is tested with TOS ?

P.S. : exactly this error : "Save Failed:Java heap space"

Hi,

Your workstation is slightly under requirements, especially because you use Windows XP system which uses up to 50% (minimum) of your memory.

Regards.

I know that Windows is specially greedy, but admit that some others soft works without problem on it... And I have no choice for this project : it's XP or... XP .
In other hand, if it is the PC, TOS might be slow as of launching.
The question is : why gradually ? I don't launch other softs and I work on one TOS job at a time, why is it slow on third or fourth launching and unusable on fifth ?... The memory of workstation is 30% to 40% used at this moment, never more. But CPU is used at 100%, and on fifth, it remain at 100% until the java error appears.

PS : and this error appears when saving, not when launching...

To launch Talend Open Studio with more memory, it's very easy : create a .bat or .sh whith the following command.

You have a machine with only 512MB, you should use

Code:

TalendOpenStudio -vmargs -Xms256m -Xmx256m -XX:PermSize=64m -XX:MaxPermSize=64m

Hi, yes me too!! But I have XP, P4 2800 and 1Gb Ram. When Talend starts, I have 600Mb free Ram. Just TOS starts it takes 75Mb of ram memory. When I open the 1° job it arrives to 100Mb. After TOS takes 5 Mb for each operation. I have seen that TOS doesn’t discharge memory when I close the jobs. TOS need a lot of memory for to work! In my pc, Tos has arrived to 200 Mb.(I saw in Windows Task Manager). When Tos arrived 200 Mb, I had 200Mb free ram memory but Tos was unusable (many minutes to anything!), so I restart TOS every time and I have a coffee break. I hope there are other solutions!

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 … tion_guide

Hi!! I'm having the same issue here, is getting very frustrating.... I ran 1.49GB of memory in a Win XP Pro, I have set up the VM Arguments within Talend to -Xms512M and -Xmx512M and still have the same problem. I work on a simple job with 5 components, and as I work it gets slower and slower to the point that I can't save and sometimes loose the code I just wrote....not fun!!! Please Please tell me how can I set up my preferences to avoid this issue!!!!

Talend 2.3.0r8623

Thanks --Gus

You can update to the last stable version.
Some memory leaks have been corrected since 2.3.0.
