What is the fastest star in our galaxy(relatively of the galactic core)?

This star has been reported to be orbiting the galaxy central black hole in 16 years, I am sure that some of the more mathematically competent correspondents can work out its speed.

Thanks.I think a freely moving star can travel faster.
