LuaLaTeX: How to speed up PDF generation?

Question

With pdflatex, I used to write pdfcompresslevel 0 and pdfobjcompresslevel 0 before the documentclass command. This would disable the PDF compression which in turn speeds up the generation of the PDF file.
However, these commands do not seem to work with LuaLaTeX. Is there a way to speed up the generation of the PDF file, e.g., by also disabling compression?

After edefpdfcompresslevel{pdfvariable compresslevel} edefpdfobjcompresslevel{pdfvariable objcompresslevel} you have the mentioned commands as in pdfTeX.
However, the speed problem is in LaTeX itself, no in compression PDF. I am using OpTeX with LuaTeX and I don't have problems with speed.

I use
RequirePackage{l3pdf}
ExplSyntaxOn
pdf_uncompress:
ExplSyntaxOff
documentclass{article}
 ....

to get uncompressed pdf. That works for all engines.
