No, I'm honestly not that knowledgable about it. Despite nominally working in linear algebra, I mainly use the computer to solve systems of low dimension that arise in other algorithms. There are no doubt a few thousand such uses in R, Octave, SageMath, etc. My only real concern is that the FlexiBLAS benchmarks appear targeted at people who use linear algebra to do large-scale linear algebra. Their smallest n=500 is larger than the matrices I usually work with. But if the numbers look the same for n=3, then there's nothing to worry about. You could steal the FlexiBLAS benchmarks and tone down "n" to test this? (You can always turn many small systems into one big system to cut down on the number of API calls, but the size of the system grows quadratically so this isn't a real strategy.)
