How to optimize cloning in new roblox update?

So basically everything has been going smooth until the new roblox update and now my barrage effect clones make the game insanely laggy.

This is the code any help on optimizing it is greatly appreciated I know this might sound lazy but it would be great if you could optimize it for me and I can review the code. I have 0 idea how to optimize and this is my last hope.

local EffectModule = require(game.ServerStorage:WaitForChild("HitEffectModule"))
local event = game:GetService("ReplicatedStorage"):WaitForChild("TheWorld").Barrage -- this is the event which fires from client to server
local TweenService = game:GetService("TweenService") -- this is a very useful function for extra effects
local Debris = game:GetService("Debris")
local Damage = 1.8
local Punched = game.Workspace.Sounds.Punched



--u can get ur own one im just using a free one as an example
local function Detect(Character)
    local Hitbox = script.Hitbox:Clone()
    Hitbox.Parent = workspace
    Hitbox.CFrame = Character.PrimaryPart.CFrame * CFrame.new(0,0,Hitbox.Size.Z/2 * -1)
    Debris:AddItem(Hitbox,.3)
    local Connection 

    Connection = Hitbox.Touched:Connect(function(hitted)
        if hitted.Parent:FindFirstChild("Humanoid") and not hitted:IsDescendantOf(Character) then
            local Enemy = hitted.Parent
            Enemy.Humanoid:TakeDamage(Damage)

            Connection:Disconnect()
            Hitbox:Destroy()
            local bv = Instance.new("BodyVelocity")
            bv.MaxForce = Vector3.new(1e6,1e6,1e6)
            bv.Velocity = Character.PrimaryPart.CFrame.LookVector * 10
            Debris:AddItem(bv,.2)
            bv.Parent = Enemy.PrimaryPart

            EffectModule.Gore2(Enemy.UpperTorso)
            Enemy.Humanoid:LoadAnimation(script.HitAnim):Play()
            Punched:Play()
            Enemy.Humanoid.WalkSpeed = 3
