Performance of the LHC, ATLAS and CMS in 2011

The path taken by the LHC team to reach 3.6 10 33 cm 2 s 1 instantaneous luminosity, and to deliver 5.6 fb 1 per experiment is summarized. The main performances of the two experiments are highlighted, in particular the way they managed to cope with the already high level of "pile-up". Selected Standard Model and top physics results are given, and the status of the limit s on the Higgs boson search by each experiment is summarized. A brief overview of the search for supersymmetry and exotic phenomena is made at the end.
