I assume, that you are working with a framerate >800Hz.
This being said, accessing the NodeMap of the camera with every image is very optimistic. I would assume this to be the bottleneck of your application and there is not much we can do about it.
I forwarded the request to our AT CX experts maybe the camera has other features we can use for what you want to achieve.
One possible solution might be to have callback funktions everytime the LineSelector changes which you can then use to read the value.
Another idea is to read the stat of all LineSelectors from a binary node and interpret this value to get all states at once.
However, if there is a soluttion to this depends on the features of the camera which we will need to have a look into.
