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

Edit the memory attributes according to your system memory availability. For example:

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

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

For more details, see http://www.oracle.com/technetwork/java/hotspotfaq-138619.html.

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
