@vpisarev @opencv-alalek Could you take a look current state? The performance test makes iterations on different input for solve/SVD, but not the same parameters each time. Is it allowed behaviour of the test? Each iteration of performance test has different behaviour internally and the test may not converge in sense of statistics distribution.
