Asynchronous while true loop

[ThePhisics101 0]

I need to keep running a loop in the background while further code is executing...

while true do
  -- code
  os.sleep(0.5)
end
print("I want this to run while the loop is running")

How would i do that without loosing much performance?

I imagine there is more to do than just printing a line so I'll assume the Thread library is what you're looking for.
