How to fix script time out allowed execution time ?

local spike = game.ServerStorage:WaitForChild("Spike")
local danger = game.ServerStorage:WaitForChild("Danger")
local X = Instance.new("NumberValue")
local Z = Instance.new("NumberValue")

while true do
    X.Value = math.random(-72,  -65)
    Z.Value = math.random(-110, 26)
    local spike2 = spike:Clone()
    local danger2 = danger:Clone()
    danger2.Parent = game.Workspace
    danger2.Position = Vector3.new(X.Value, danger2.Position.Y,  Z.Value )
    spike2.Position = Vector3.new(X.Value, spike2.Position.Y,  Z.Value )
    wait(1.5)
    spike2.Parent = game.Workspace
    danger2.Parent = nil
end
