Even four times as slow as Magma is still fantastic (for GCDs).
While gcd's are not my personal interest, I keep an eye on the
subject.
I am interested in progresses, and would be willing to promote some
cooperation ideas to the Singular
group, if you have a good plan.

Related to this whole thread, note there are various web options from
the Ms which, though more likely generated because the technology was

For those still interested in this thread, I have completed the Magma
timings again on an identical machine which does not suffer from the
timing irregularities of the other machine. I've done this very

Maybe polybori is the only package (al least in sage), which uses
scons and sonames. Other packages I know, either do not make use of
the soname or use libtool (the latter ist unfortunately not supported
by scons).

I've been doing some tinkering with the congruence subgroups code
