  sPHENIX is a new experiment that is being constructed at the Relativistic
Heavy Ion Collider at Brookhaven National Laboratory. The primary physics goals
of sPHENIX are to measure jets, their substructure, and the upsilon resonances
in $p$$+$$p$, $p$+Au and Au+Au collisions. To realize these goals, a tracking
system composed of a time projection chamber and several silicon detectors will
be used to identify tracks that correspond to jets and upsilon decays. However,
the sPHENIX experiment will collect approximately 200 PB of data utilizing a
finite-sized computing center; thus, performing track reconstruction in a
timely manner is a challenge due to the large occupancy of heavy-ion
collisions. The sPHENIX experiment, its track reconstruction, and the need for
implementing faster track -fitting algorithms, such as that provided by the A
Common Tracking Software package, into the sPHENIX software stack are
discussed.
