I am sorry, I have a hard time accepting this level of detail, acknowledging it was half a decade ago.

In a nutshell, you content that FreeBSD running on the same hardware as "a linux" performed better with camera operations. However, you did not specify even a specific camera model, or the interface(s) used to interact with the camera.

I have zero issue accepting that a BSD is better than a linux at things, pretending otherwise is foolish. However, this specific example isn't tracking.
