Attachment was probably stripped. Anyways, I guess that it's the same as on the JIRA page.[1] If so, it's not very telling. > > I have tried this with 3.3 and 3.6.1, both versions perform similarly.

Best would be to set up unit tests that replicate your usage of the class, and provide answers to the following questions: * What kind of performance do you expect? Did you compare with other libraries? * Did you investigate how the performance varies with matrix size? * Do you observe the same slow-down with other decomposition classes? * Is the behaviour similar with square matrices? * Which matrix implementation do you use?
