Hi,

 

 

difficult to tell without knowing your workspace in detail, but some general tips are:

 

• Remove as many attributes as possible, as early as possible in your workflow (AttributeKeeper is your friend)
• Beware of large lists that are kept "indefinitely" (AttributeRemover is your friend)
• Don't store geometries in an attribute, e.g. GeometryExtractor
• Beware of blocking transformers, e.g. FeatureMergers, they fill up memory quickly

If you rely on a lot of FeatureMergers and the like, consider staging your processing by first loading everything into a proper database (SQLite or PostgreSQL are good and free alternatives) and then do joins on the database side using e.g. a SQLCreator rather than a csv reader. With proper indexing it is usually a lot faster and much more memory efficient.
