Yes, I know. I just needed to start with something "solid". If running at the lowest performances is stable, it gives me a reference. I had time to test another commit in the branch, but since I'm not at home, I can't say if all the commits you had identified are in. I'll probably continue tonight.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
