It does take some time, but far less than in pure Singular according to Ulrich's timings (which is still much faster than my [faster] CPU). Although from looking at the multivariate code, there should really be no overhead. So maybe my statement with conversions is not correct. > The polynomials > in Singular are not optimised for arithmetics but for Gröbner basis > computations, which (as I was told some time ago) are two totally > different things. > I also remember reading the same thing, but I cannot seem to find a reference for it. From the like I posted, there also seems to be something said for dense multivariate polynomials. However, this suggests that we should figure out some way to quickly convert to a system that is much better at multiplying polynomials.
