Is this a good way to session lock?

I’m trying to prevent data loss by making it so people’s stats won’t load until it has been confirmed they save.

This code should 100% work, but I’m sure it will slow down the datastores.

local session=game:GetService("DataStoreService"):GetDataStore("Sessions")

local function save(plr)
-- save stats
  session:SetAsync(plr.UserId,false)
end

game.Players.PlayerAdded:Connect(function(plr)
  local insession=session:GetAsync(plr.UserId)
  if insession then plr:Kick("Your data is being loaded.") return end -- would ideally write a wait loop here instead of kicking them
  session:SetAsync(plr.UserId,true)
  repeat plr.AncestryChanged:wait() until not plr.Parent
  save(plr)
end)

game:BindToClose(function()
  for i,v in pairs(game.Players:GetPlayers()) do
    if v.Parent then
      save(v)
    end
  end
end)
