  VERITAS is a ground-based gamma-ray instrument operating at the Fred Lawrence
Whipple Observatory in southern Arizona. With an array of four imaging
atmospheric Cherenkov telescopes (IACTs), VERITAS is designed to measure gamma
rays with energies from $\sim$ 85 GeV up to > 30 TeV. It has a sensitivity to
detect a point source with a flux of 1$\%$ of the Crab Nebula flux within 25
hours. Since its first light observation in 2007, VERITAS has continued its
successful mission for over seven years with two major upgrades: the relocation
of telescope 1 in 2009 and a camera upgrade in 2012. We present the performance
of VERITAS and how it has improved with these upgrades.
