save simple document as pdf under linux is huge

It will create a pdf file which is 13.7mb, while the document is 20k.
when saving html only containing “token:12344” as pdf, the pdf is 12mb.

When mergeing two documents, the final pdf file size will be double (24mb).

Can you please clarify your issue and provide some sample file with code?

The latest one doesn’t have the issue.
