Extreme lag issue

[ilzroV1]

My game has this really weird issue that sometimes, the game lags a LOT. And I don’t mean FPS. Everyone can still move around normally, but they can’t use any attacks properly because they are delayed by like 30 seconds (The attacks are serversided.)
Eventually, the lag ends and people can use attacks normally.

The weird thing is, it happens in random times. There are days where it doesn’t happen at all, days where it happens for 5 minutes, days where it lasts forever etc.
It’s really been bugging me.

Here’s the client input script:

local UIS = game:GetService("UserInputService")
local player = game.Players.LocalPlayer
local mouse = player:GetMouse()
local character = player.Character or player.CharacterAdded:Wait()
local root : Part = character:WaitForChild("HumanoidRootPart")

script.InputServer.Enabled = true

UIS.InputBegan:Connect(function(input, GPE)
	if not GPE and input.KeyCode.Name ~= "Unknown" then
		script.Input:FireServer(input.KeyCode.Name, root.CFrame)
	end
end)
UIS.InputEnded:Connect(function(input, GPE)
	if not GPE and input.KeyCode.Name ~= "Unknown" then
		script.Input:FireServer(input.KeyCode.Name.. "_UP", root.CFrame)
	end
end)
script.Input.OnClientEvent:Connect(function(input)
	script.Input:FireServer(input)
end)

mouse.Button1Down:Connect(function()
	if script.Parent:WaitForChild("MobileSupport").Enabled == false and not game.Players.LocalPlayer.Character:FindFirstChildWhichIsA("Tool") then
		script.Input:FireServer("M1")
	end
end)

script.ChildAdded:Connect(function(child)
	if child.Name == "Attacks" then
		game.ReplicatedStorage.GUI.NewKeybinds:Fire(child)
	end
end)

And here’s the server input script:

local attacks = script.Parent:WaitForChild("Attacks")
local player : Player = script.Parent.Parent.Parent
local character : Model = player.Character or player.CharacterAdded:Wait()
local dataStore = require(game:GetService("ReplicatedFirst").Modules.DataStores)
local stand : string = dataStore:GetData(player, "Stand")

function validate(key)
	stand = dataStore:GetData(player, "Stand")
	if (character.Humanoid.Health <= 0 or character:HasTag("Disabled") or character.RagdollTrigger.Value == true) then return false end
	
	if key == "T" or key == "F" or key == "B" then
		if stand == "King Crimson" then
			return true
		end
	end
	if key == "E_UP" or key == "X_UP" or key == "P" then
		return true
	end
	if script.Parent.Attacks:FindFirstChild(key) and not player:WaitForChild("Cooldowns"):FindFirstChild(key) and not character:HasTag("Active") and not character:HasTag("Stunned") and character.HumanoidRootPart.Anchored == false then
		return true
	else
		return false
	end
end

script.Parent.Input.OnServerEvent:Connect(function(firedPlayer, key, rootCFrame)
	stand = dataStore:GetData(player, "Stand")
	if firedPlayer ~= player then
		firedPlayer:Kick("You were kicked from the game for suspicious activity. If you believe that this kick was unfair, please contact the owner of the game.")
	else
		if validate(key) then
			script.Parent.Attacks[key]:Fire(player, rootCFrame)
		end
		if key == "N" and not player:WaitForChild("Cooldowns"):FindFirstChild(key) and not character:HasTag("Active") and not character:HasTag("Stunned") and character.HumanoidRootPart.Anchored == false then
			game.ReplicatedStorage.Effects.Quote:Fire(player)
		end
	end
end)

This is a game breaking issue, I would really appreciate any help.

i have no idea what kind of datastore module you are using, but its not a good idea to do anything with a datastore this often

your issue is probably related to networking, try making your code more client sided

alright i’ll try replacing the datastore check with something else so it doesn’t have to check that often
