So basically, I made a turret that detects when a humanoid is in its range, and it will fire missiles at it, that fly towards the humanoid using RocketPropulsion. It works just fine, however when there are many humanoids in the place (NOT within he turrets range!), the missiles just get slow. And I mean, really slow. The moment I get rid of all the humanoids, it returns to normal speed. And its only the missiles that are slow; the rest of the place moves around and runs just fine.

So yeah, why is this happening? The game is a MOBA by the way, so if you know what that means, this effect occurs the moment minions spawn. Here's the code if you want to see the turret script, there will be some things you wont understand though :

local arr = { }
local delay = 2-- speed of shooting
local tempdelay = 0
local previouschar
local range = 52
while wait(0.1) do
	arr = { }
	
	
	for _,v in pairs(script.Parent:GetChildren()) do
		if v:IsA("ObjectValue") then table.insert(arr,v) end
	end
	
	if #arr > 0 then
		local ind = 1
		if (Workspace:FindFirstChild(arr[1].Name) == nil) then 
			arr[1]:Destroy()
		else
			local minrange = (script.Parent.Torso.Position - Workspace[arr[1].Name].Torso.Position).magnitude
			for i = 1,#arr do
				local r = (script.Parent.Torso.Position - Workspace[arr[i].Name].Torso.Position).magnitude
				if (r < minrange and r <= range) then
					minrange = r
					ind = i
				end
			end
			if minrange <= range then
				local char = Workspace:findFirstChild(arr[ind].Name)
				if char ~= nil then
					if game.Players:FindFirstChild(char.Name) ~= nil then
						if game.Players[char.Name]:findFirstChild("Ding") == nil then
							local dng = script.Parent.Ding:Clone()
							dng.Parent = game.Players[char.Name]
							dng:Play()
						end
						script.Parent.DetectorV.BrickColor = BrickColor.Red()
					else
						if (previouschar ~= nil) then
							if (game.Players:findFirstChild(previouschar.Name) ~= nil) then
								if game.Players[previouschar.Name]:findFirstChild("Ding") ~= nil then
									game.Players[previouschar.Name].Ding:Destroy()
								end
							end
						end
						script.Parent.DetectorV.BrickColor = BrickColor.Green()
					end
					if tempdelay >= delay then
						tempdelay = 0
						local sht = script.Parent.Shoot:Clone()
						sht.Parent = char.Torso
						sht:Play()
						local hitsound = script.Parent.Hit:Clone()
						local blast = script.Parent.Diamond:Clone()
						blast.Script:Destroy()
						blast.Transparency = 0.3
						blast.CanCollide = false
						blast.Anchored = false
						blast.Name = "Blast"
						blast.Parent = script.Parent
						blast.CFrame = script.Parent.Diamond.CFrame
						local rp = Instance.new("RocketPropulsion",blast)
						rp.ThrustP = 3 * char.Humanoid.WalkSpeed
						rp.MaxSpeed = 3 * char.Humanoid.WalkSpeed
						local targ = Instance.new("StringValue",blast)
						targ.Name = "Target"
						targ.Value = arr[ind].Name
						local fire = Instance.new("Fire",blast)
						if blast.BrickColor.Name == "Bright green" then
							fire.Color = Color3.new(0.5,1,0)
							fire.SecondaryColor = Color3.new(0,1,0)
						else
							fire.Color = Color3.new(0.5,0,1)
							fire.SecondaryColor = Color3.new(0,0,1)
						end
						hitsound.Parent = blast
						local sc = script.BlastScript:clone()
						sc.Parent = blast
						sc.Disabled = false
					end
					previouschar = char
				end
			end		
		end
	else
		script.Parent.DetectorV.BrickColor = BrickColor.Yellow()
	end
	tempdelay = tempdelay + 0.1
end

Here is the Missile Script :

local diam = script.Parent
local rp = diam:findFirstChild("RocketPropulsion")
local targ = diam:findFirstChild("Target")
local hit = diam:findFirstChild("Hit")
if (rp == nil or targ == nil or hit == nil) then
	print("Lacking rocketpropulsion or target or sound")
	script.Parent:Destroy()
end

local char = Workspace:FindFirstChild(targ.Value)
if char ~= nil then
	rp.Target = char.Torso
	rp:Fire()
	print("Fired")
end

rp.ReachedTarget:connect(function()
	if char ~= nil then
		char.Humanoid:TakeDamage(10)
		hit:Play()
	end
	script.Parent:Destroy()
end)

Thanks in advance!
