1. You may convert the serial file to multifile system using a partition by key, if it is a serial file.
2. You may filter out all the records from the file that are unwanted for the process. Elimination of records helps the cause.
3. If there are joins with any tables/files, try to use look up files for smaller tables/files.
Also you should use the larger file as the driver port for joins with bigger tables/files.
4. Use in memory sort for smaller file joins.
5. By any chance if you are unloading from a table, you may use order by in the SQL which eliminates use of Sort component in the graph.
I hope these helps. Please correct me if I am wrong.
