------------------------------

Hi.

Is this a bug report or a usage question?
In the latter case, you should post to the [user mailing list|http://commons.apache.org/mail-lists.html].

Also, be sure to report issues using the latest version of the library (at least v3.6.1 or even better the developement version). Thanks.

> We use SingularValueDecomposition(RealMatrix) and getSolver() methods.
> This seems to be taking time for large matrices, refer to attached picture.
> Example:925*161
> I have referred to release notes of the library, It seems there are no major changes related to SVD.
>  
> Is there any way to improve performance,
