The Blender addon does it single threaded too, and in Python on top of that.
It sounds to me like the algorithm to detect instances is very very complicated. How does it work, in detail? I would first check if there's a faster alternative before thinking about multithreading.

Translate time 17 seconds.

This seems very long to me.
The Blender addon exports 12000 particle instances in 0.2 seconds, and 12000 objects with shared meshes (alt+D copies) in 2.8 seconds.

How does your current algorithm for detecting which meshes can be instanced work?

Cycles has code to ensure that the normal stays valid after bump/normal mapping is applied: https://developer.blender.org/D2574
Maybe this is responsible for the difference?

Please upload the scene.

Select the camera, go to camera properties, LuxCore imagepipeline panel, and enable transparent film.

But inside Blender I don't seem to have an option to adjust the gamma of an image texture.

If you use the normal map option, gamma is set to 1 by the Blender addon.

Maybe the "remove doubles" step could be made optional?
In the Blender addon it would be disabled then, to make the behaviour the same as in Cycles.

It would be nice if the tool checks the availability and turns it off automatically.

This was working for a while, but the LuxCore API was changed I think and I'll have to look up how to check OptiX availibility now.

If it happens in any scene, it should be easy to upload one, right?

Awesome, and thanks for providing the scene!
