Performance highlights in ATLAS

The Run-2 data taking period of the LHC ended in 2018 and Run-3 is currently ongoing. While the new data are being recorded, the precision results and new methods have been applied in the reconstruction workflows in ATLAS. In this review a walk-through of recent achievements for each of the objects is taken, tracking, muons, electrons/photons, jets/missing transverse momentum, flavor and jet tagging, and hadronically decaying τ-leptons will be discussed in this order. The highlights will be on updated results for Run-2, which in most cases form the basis for Run-3 reconstruction, including new techniques that will be used in Run-3 or in the future.
