Editing the memory and JVM settings

To gain in performance at runtime and when launching Talend Studio you can edit the memory settings in the .ini file.

By default, the .ini file sets the following JVM parameters:

--launcher.XXMaxPermSize512m
-vmargs
-Xms64m
-Xmx768m
-Xdock:icon=../Resources/talend.icns
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Dosgi.instance.area.default=../../../workspace
-Dfile.encoding=UTF-8

Note: The settings of the .ini configuration file will only impact the performance of Talend Studio, not the job execution itself.

Procedure

Find and open the Talend-Studio-macosx-cocoa.ini file.
Edit the memory attributes according to your system memory availability. For example:

-vmargs -Xms512m -Xmx1536m -XX:MaxMetaspaceSize=512m

Information noteTip: For big projects, you may need to increase Xmx to 4096m.

Example

With 8 GB of memory available on 64-bit system, the optimal settings can be:

--launcher.XXMaxPermSize512m
-vmargs
-Xms2014m
-Xmx4096m
-Xdock:icon=../Resources/talend.icns
-XstartOnFirstThread
-Dorg.eclipse.swt.internal.carbon.smallFonts
-Dosgi.instance.area.default=../../../workspace
-Dfile.encoding=UTF-8
