Given the example, I believe that the original should have been edited. The first question was basically "help me with my performance problem". The first question got no answers, but got some comments that might be pointing you in another direction. Whether or not those are right is another matter.
That said, it seems that you've come to the conclusion on your own that the problem is not Samba, so your initial question was asked on a false assumption. Because of that, the original question, as asked, holds no practical value. Instead of abandoning it, I feel that it should be edited to more accurately reflect the situation at hand, since it's about the same underlying performance issue.
