[Visualization] High memory consumption of visualization for large invoices

JannickWeisshaupt opened this issue 3 years ago · 4 comments

The visualization files contain a single page-sequence, which contains all content.
This however can lead to very high >2GB memory consumption for large documents with, e.g. many line trade items.
Apache FOP documentation explicitly recommends to use multiple page sequence, see https://xmlgraphics.apache.org/fop/0.95/running.html#memory

For example an invoice with 2000 simple line trade items will lead to a memory consumption of ~500MB.

Is there somewhere available example document with that many lines that could be used for testing?
