Hi again,

if the problem I just described is indeed affecting you, I might have interesting new \
info:

I found http://sourceforge.net/tracker/?func=detail&aid=3043968&group_id=159897&atid=813673 \
which mentions a changed behaviour in aria2c 1.10.x, compared to 1.9.x. Indeed, when \
I try the mentioned options "--max-connection-per-server=4 --min-split-size=1M" \
aria2c behaves again as I would expect it:

As the log excerpt shows, aria2c contacts not only one server, and it finishes the \
download in about 4 seconds (instead of one minute) even though the slow utexas.edu \
mirror was used (among others).

That's how it should be.

So, if you see the same happening, and if you are indeed using a new aria2c (1.10.x), \
then one should figure out how zypper/yast can use the right options (or if this is a \
bug).
