How to make this door smoother?

http://prntscr.com/63quna - I have no clue how to add the script here like it is in the Studio, so I screenshoted it, is there any way to make it smoother...?Like just to close and open smoother?

Since I'm too lazy to rewrite all of that code, I'll explain my method instead, using placeholder CFrame stuff.

waits in ROBLOX always way at least .03 seconds. Your waits do that, too, even though you set them smaller. This is a hard limit that cannot be changed globally.

The easiest way to go about this is to use something called a time delta:

--This is a purely linear interpolation. It may not look very pretty, but it will work.
local openTime = 4 --seconds

local openTarget = CFrame.new(0, 5, 0)*CFrame.Angles(0, math.pi, 0)
local closedTarget = CFrame.new(0, -3, 8)

local deb = false
local open = false

local door = script.Parent

function toggleDoor()
	local dt = 0
	local t = tick()

	initial = open and openTarget or closedTarget
	final = open and closedTarget or openTarget
	
	local done = false
	while not done do
		dt = tick() - t
		local newTarget = {}
		if dt/openTime < 1 then
			for i = 1, 12 do
				newTarget[i] = initial[i] + (final[i] - initial[i])*(dt/openTime)
			end
			-- initial + (final-initial)*(percentage) = initial + (totalDisplacement)*(percentage)
			-- = initial + percentageDisplaced = currentPosition
		else
			newTarget = final
			done = true
		end
		door.CFrame = CFrame.new(newTarget[1], newTarget[2], newTarget[3],
									newTarget[4], newTarget[5], newTarget[6],	
									newTarget[7], newTarget[8], newTarget[9],
									newTarget[10], newTarget[11], newTarget[12],)
		wait()
	end
end

do
	local x, y, z, R00, R01, R02, R10, R11, R12, R20, R21, R22 = openTarget:components()
	openTarget = {x, y, z, R00, R01, R02, R10, R11, R12, R20, R21, R22}

	local x, y, z, R00, R01, R02, R10, R11, R12, R20, R21, R22 = closedTarget:components()
	closedTarget = {x, y, z, R00, R01, R02, R10, R11, R12, R20, R21, R22}
end

script.Parent.ClickDetector.MouseClick:connect(function()
	if deb then return end
	deb = true
	toggleDoor()
	open = not open
	deb = false
end)
