vite loading react app extremely slow (like 10 seconds delay)

[hushed coral]

it's a react route app

main.tsx

import { createRoot } from "react-dom/client";
import "./index.css";
import { App } from "./App.tsx";
import { BrowserRouter, Routes, Route } from "react-router-dom";

createRoot(document.getElementById("root") as HTMLElement).render(
  <BrowserRouter>
    <Routes>
      <Route path="/*" element={<App />} />
    </Routes>
  </BrowserRouter>
);

client.tsx just contains literally a table

What is in App.tsx ? Do you use icon libraries ?
