Am i using RemoteEvent Properly?

Hi i'm Having a BIG problem with my First RemoteEvent Tool, and when i say FIRST i mean.. Works fine, but i could do better and increase Performance

uuh.. sorry if my coding seems confusing... (the reason why i need help) also i'm asking for help because i just CAN'T FIND OUT HOW TO DECREASE THE LAG!

Local Script:

wait()
local Tool = script.Parent
Player = game.Players.LocalPlayer
mouse = Player:GetMouse()
char = Player.Character
repeat wait() until Player.Character
hum = char.Humanoid	
repeat wait() until char.Humanoid

local en = true
Tool.Activated:connect(function()
	if not en then return end
	local point = mouse.Hit.p
	en = false
	Tool.FireBlast:FireServer(point)
	en = true
end)

Script:

local Tool = script.Parent
local Object = game:GetService('ServerStorage'):WaitForChild("Blast_Model")

local R6RightAnim = Tool.R6Content.RightBlast
local R6LeftAnim = Tool.R6Content.LeftBlast

local R15RightAnim = Tool.R15Content.RightBlast
local R15LeftAnim = Tool.R15Content.LeftBlast

local Enabled = true

local Cooldown = 0.01 	--//Trust me you don't wanna put this to 0 if people use auto clicker, Default is [0.01]
local Blast_Speed = 100 
local Damage = 5 		
wait(.2) --//Don't Change

function NewBlast(Damage,Speed,Target,StartPos,pName)
	local Blast = Object:Clone()
	Blast:WaitForChild('Damage').Value = Damage
	Blast.Parent = workspace
	Blast.CFrame = StartPos
	game.Debris:AddItem(Blast,5)
	Blast.Velocity = ((Target - Blast.Position).unit) * Speed
	local force = Instance.new'BodyForce'
	force.force = Vector3.new(0, Blast:GetMass()*workspace.Gravity, 0)
	force.Parent = Blast
	local BlastColor = ColorSequence.new(Blast.Color)
	Blast.Trail.Color = BlastColor
	
	Blast:WaitForChild('Owner').Value = pName
	Blast:WaitForChild('Damage').Value = Damage
	Blast:WaitForChild('GeneralScript').Disabled = false
end

function PlayAnimation(hum, anim)
	local Animation = hum:LoadAnimation(anim)
	Animation:Play()
end

function CreateSound(audioID,audioVolume,pitch,debris,paren)
	local link = 'rbxassetid://'
	local Audio = Instance.new('Sound')
	Audio.SoundId = link..audioID
	Audio.Volume = audioVolume
	Audio.PlaybackSpeed = pitch
	Audio.Parent = paren
	Audio.Name = math.random(1, 1000000) --//Names the Audio Randomly a Number from 1 to 1000000
	Audio.EmitterSize = 3.5
	game.Debris:AddItem(Audio,debris)
	
	Audio:Play()
end

Tool.FireBlast.OnServerEvent:connect(function(Player,p)
	local humanoid = Player.Character:WaitForChild('Humanoid')
	if humanoid and Enabled == true then
		Enabled = false
		if (humanoid.RigType == Enum.HumanoidRigType.R6) then
			local RandomPart = math.random(1,2)
			if RandomPart == 1 then wait(.1)
				NewBlast(10,125,p,CFrame.new(Player.Character['Right Arm'].RightGripAttachment.WorldPosition.X,Player.Character['Right Arm'].RightGripAttachment.WorldPosition.Y,Player.Character['Right Arm'].RightGripAttachment.WorldPosition.Z),Player.Name)
				PlayAnimation(humanoid, R6RightAnim)
				CreateSound(145681580,.3,1.1,0.8,Player.Character.Torso)
				CreateSound(853857055,.5,1,1,Player.Character.Torso)
			else wait(.1)
				NewBlast(10,125,p,CFrame.new(Player.Character['Left Arm'].LeftGripAttachment.WorldPosition.X,Player.Character['Left Arm'].LeftGripAttachment.WorldPosition.Y,Player.Character['Left Arm'].LeftGripAttachment.WorldPosition.Z),Player.Name)
				PlayAnimation(humanoid, R6LeftAnim)
				CreateSound(145681580,.3,1.1,0.8,Player.Character.Torso)
				CreateSound(853857055,.5,1,1,Player.Character.Torso)
			end
		end
		
		
		if (humanoid.RigType == Enum.HumanoidRigType.R15) then
			local RandomPart = math.random(1,2)
			if RandomPart == 1 then wait(.1)
				NewBlast(10,125,p,CFrame.new(Player.Character['RightHand'].RightGripAttachment.WorldPosition.X,Player.Character['RightHand'].RightGripAttachment.WorldPosition.Y,Player.Character['RightHand'].RightGripAttachment.WorldPosition.Z),Player.Name)
				PlayAnimation(humanoid, R15RightAnim)
				CreateSound(145681580,.3,1.1,0.8,Player.Character.UpperTorso)
				CreateSound(853857055,.5,1,1,Player.Character.UpperTorso)
			else wait(.1)
				NewBlast(10,125,p,CFrame.new(Player.Character['LeftHand'].LeftGripAttachment.WorldPosition.X,Player.Character['LeftHand'].LeftGripAttachment.WorldPosition.Y,Player.Character['LeftHand'].LeftGripAttachment.WorldPosition.Z),Player.Name)

	end
	wait(Cooldown)
	Enabled = true
end)

This is a Free model so you can take it:

"What to do now?" Change/Remove/Edit some lines there if that will help to remove the LAG

Hey uh.. RemoteEvents should be placed at ReplicatedStorage... uh.. ReplicatedFirst?... or it doesn't matter if it has been placed inside the Tool?

*Important: My Network isn't bad, i can prove it, when i tested it in the first time the delay was from 1 to 3 seconds. so i had a very good idea, why not take a free model tool wich uses RemoteEvent and compare the delay? the free model had a Delay of 0.1 to 0.2 Seconds. so the problem isn't in my Network, the problem is in my Scripting.

and i'm not requesting a script from anyone, i just want some help to figure out how to properly use RemoteEvents.
