Go seems to have issues with the database drivers, maybe because of the 1.1 update?
It was quite fast in the previous iterations of the test which used Go 1.0 afaik.
In the previous round, we did not have Go implementations of the database test, so this is new community-contributed database test code here. However, see my post elsewhere in this thread [1] about the community's work to resolve the issues afflicting that test.
