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

  1. Find and open the Talend-Studio-win-x86_64.ini file.
  2. 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
