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:
-vmargs
-Xms64m
-Xmx768m
-XX:MaxPermSize=512m
-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:
-vmargs
-Xms1024m
-Xmx4096m
-XX:MaxPermSize=512m
-Dfile.encoding=UTF-8
