The second LHC run has started in June 2015 with a p-p center-of-mass collision energy of 13 TeV and ATLAS has taken 3.2 fb-1 of data at the new energy in 2015. In this talk the improvements made to the ATLAS experiment during the two-year shutdown 2013/2014 will be discussed. Furthermore, reconstruction algorithms of tracks, e/γ, muons, taus, jets and flavour tagging have been improved for Run-2. Reconstruction efficiency, isolation performance, transverse momentum resolution and momentum scales are measured in various regions of the detector and in momentum intervals enlarged with respect to those measured in the Run-1. The performance of the upgraded detector and the new reconstruction algorithms measured using these data taken in 2015 will be discussed.
