Achim - As per comment #13 and #20 I don't believe this fix will solve your particular problem completely.
However now the bug has been linked to a stable release update, it would probably be inappropriate to re-open. Perhaps we should change the description to clarify that this bug only fixes the re-introduction/regression of bug 861061 (in Unity 5.10).
I expect another bug should be opened to continue working on the remaining performance problems.
