System Information
Operating system: Windows 11

Blender Version
Broken: b2196ebe28
Worked: b2196ebe28

Short description of error

There does not seem to be a much of render time difference between a scene is fully rendered with Freestyle edges or most of the scene is excluded from Freestyle via collections.

Exact steps for others to reproduce the error

Load the attached scene.

Render the frame and take a note of the render time

Disable the collection filtering in Freestyle using the Frestyle options in the View Layer tab

Render the frame

Compare the time results, the values are very close which makes me think that the edges are still calculated.

Delete all the objects in "NO.FREESTYLE" collection, just delete them from the scene so you have only one gear object left in the scene

Render the scene which should render the gear with Freestyle, the result should be much faster.

FreeStyle is no longer in active development and, therefore, is no longer being improved.
The current replacement is the Line Art modifier (for Grease Pencil objects).

Analyzing the file shown. I noticed free style still needs to import all the geometry to create maps like occlusion.

For that, among other things, it needs to apply modifiers, which can be quite slow.

So thanks for the report but while we do continue to work on improving performance in general, potential performance improvements are not handled as bug reports.

To improve performance, consider using less complex geometry, simpler shaders and smaller textures.
