this is the time the first time I execute it

and this is the second one

and the third one

so I'm not sure there's a performance regression...

I might do a callgrind run for this.

I don't see a point in opening a new bug here. Yes, this is Fileopen and that is Editing, but underlying issue may be the same, and it wasn't determined there. 
So, I'd close as a duplicate of Bug 86714, write this info there and focus to solve that one. 
I still may be wrong but at least: is bibisectRequest really possible here? If not, please remove.
