Am I using Parallel Lua correctly?

Help and Feedback Scripting Support
#1

I learned that Parallel Lua would increase performance but I am not really seeing a difference when using it.

local RunService = game:GetService("RunService")

local character = script.Parent.Parent
local humanoid = character:WaitForChild("Humanoid")
local HumanoidRootPart = character:WaitForChild("HumanoidRootPart")

local Heroes = workspace:WaitForChild("Heroes")
local target = nil

local raycastParams = RaycastParams.new()
raycastParams.FilterDescendantsInstances = {character}
raycastParams.FilterType = Enum.RaycastFilterType.Exclude

local function GetNearestTarget()
	local nearestDistance = math.huge

	for i,v in Heroes:GetChildren() do
		if v:IsA("Model") and v.PrimaryPart then
			local humanoid = v:FindFirstChildOfClass("Humanoid")
			local distance = (HumanoidRootPart.Position - v.PrimaryPart.Position).Magnitude

			if humanoid and humanoid.Health > 0 and distance < nearestDistance then
				nearestDistance = distance
				target = v
			end
		end
	end
end

HumanoidRootPart.Touched:Connect(function(hit)
	if not hit:IsDescendantOf(character) then
		local speed = HumanoidRootPart.AssemblyLinearVelocity.Magnitude

		if speed >= 1 then
			humanoid.Jump = true
		end
	end
end)

RunService.Heartbeat:Connect(function()
	task.desynchronize()
	GetNearestTarget()
	
	if target and target.PrimaryPart then
		task.synchronize()
		humanoid:MoveTo(target.PrimaryPart.Position)
		task.desynchronize()
		
		local rayOrigin = HumanoidRootPart.Position
		local rayDirection = HumanoidRootPart.CFrame.LookVector * 2
		local raycast = workspace:Raycast(rayOrigin, rayDirection, raycastParams)
		
		if raycast then
			task.synchronize()
			humanoid.Jump = true
			task.desynchronize()
		end
	end
end)
