Pathfinding NPC slows down as it approaches the player, please help fix?

I am currently making an RPG like game, where players attack NPCs for coins. I have a pathfinding script that will allow the NPC to move towards the player. The problem is, actually there are a few problems, let me list them down.

1.The NPC can never outrun the player, no matter the walkspeed 2.The NPC slows down as it approaches the player 3.As it gets near the player, the movement gets choppy, and looks likes its teleporting.

I tried many solutions, but they didn't help. Here is my code, if anybody knows a fix, please write down an answer.

local npc = script.Parent
local npcRoot = npc:FindFirstChild('HumanoidRootPart')
local humanoid = npc:FindFirstChild('Humanoid')


local pathfindingService = game:GetService('PathfindingService')
local maximumRange = math.huge



local function moveToDestination()
	for _, plr in pairs(game.Players:GetPlayers()) do
		if plr and plr.Character and plr.Character.Humanoid.Health > 0 then
			local character = plr.Character
			local humanoidRoot = character:FindFirstChild('HumanoidRootPart')
			if humanoidRoot and (npcRoot.Position-humanoidRoot.Position).Magnitude <= maximumRange then
				local path = pathfindingService:CreatePath()
				path:ComputeAsync(npcRoot.Position, humanoidRoot.Position)
				
				local waypoints = path:GetWaypoints()
				if path.Status == Enum.PathStatus.Success then
					for _, waypoint in ipairs(waypoints) do
						if waypoint.Action == Enum.PathWaypointAction.Jump then
							humanoid:ChangeState(Enum.HumanoidStateType.Jumping, true)
						end
						humanoid:MoveTo(waypoint.Position)
					end
				end
			end
		end
	end
end



while true do
	wait(0.1)
	moveToDestination()
end
