-> Again, if you don't go native, you won't get the speed. I don't think why is covered in the pictures so I'll write it as best as I can in one sentence.
-> For example, a sensor rate is normalized so that all tables give about the same samples per second for the JAVA API.
The only way to get more is to go native. As a developer you know what this means.
