using delay() wont wait 1 second after the first time?

while true do
    wait()
print("fast print")
delay(1,function()
    print("slow print")
end)
end

I have a simple setup for delay. I want "fast print" to print as fast as the while true do loop and also have "slow print" only print every one second.

when the game runs slow print only waits once then it prints as fast as the fast print.

am I doing something wrong?
