High luminosity operation of the LHC is expected to deliver proton-proton collisions to experiments with average number of proton-proton interactions reaching 200 every bunch crossing. Reconstruction of charged particle tracks with current algorithms, in this environment, dominates reconstruction time and is increasingly computationally challenging. We discuss the importance of taking computing costs into account as a critical part of future tracker designs in HEP as well as the importance of algorithms used.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
