1.Tparalleize :-
When a Job consists of several sub jobs (tRunjob component), we might want to execute some of them in parallel and then synchronize the execution of the other Subjobs at the end of parallel execution.
To achieve that we simply use the tParallelize component to orchestrate all the Subjobs to be executed.
Follow the below steps to increase the JVM
1. In the Run view, the Advanced settings tab, select the Use specific JVM arguments checkbox.
2. Select the Use specific JVM arguments to enable the configuration.
3. Now double click on the individual arguments and specify the JVM arguments accordingly
-Xms represents the minimum and -Xmx represents the maximum JVM arguments
3. Multi-thread execution:-
When the Project settings check box is selected, the Multi-thread execution checkbox could be grayed out and become unavailable. In this situation, clear the Use project setting check box to activate the Multi-thread execution checkbox.
4.Removing data column not used of the ETL process
By the removing the columns of the database, other input sources would reduce the time of loading the data from database component. When multiple database components is used as lookup component in tMap, this plays a vital effect in the loading the data at a faster rate.

2.Configuring the JVM parameter of an individual job
In Talend Open Studio it is possible to specify the number of MB used in each streaming chunk. The default is a minimum of 256MB and a maximum of 1024 MB, but we increase the amount if we have more memory to devote.Follow the below steps to increase the JVM
1. In the Run view, the Advanced settings tab, select the Use specific JVM arguments checkbox.
2. Select the Use specific JVM arguments to enable the configuration.
