slower session lookup in prod than local

not sure if anyone else has encountered this issue (next-auth stable v4) but it's weird to see that calling /session locally takes 30-40ms (pic 1) but on production it goes up to 400-500ms (pic 2) (which I think is because it's not cached? not using the provider?) I'm attaching screenshots and my root layout.tsx Note: I'm NOT using a local db on local dev, both instances are connecteed to planetscale through regular connection strings

the layout.tsx

// Default created by T3
import "~/styles/globals.css";

import { GeistMono } from "geist/font/mono";
import { GeistSans } from "geist/font/sans";
import { AuthProvider } from "~/components/auth-provider";
import { TRPCReactProvider } from "~/trpc/react";

export const metadata = {
  title: "Create T3 App",
  description: "Generated by create-t3-app",
  icons: [{ rel: "icon", url: "/favicon.ico" }],
};

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html lang="en">
      <body className={`font-sans ${GeistSans.variable} ${GeistMono.variable}`}>
        <AuthProvider>
          <TRPCReactProvider>{children}</TRPCReactProvider>
        </AuthProvider>
      </body>
    </html>
  );
}

// Default created by T3
import "~/styles/globals.css";

import { GeistMono } from "geist/font/mono";
import { GeistSans } from "geist/font/sans";
import { AuthProvider } from "~/components/auth-provider";
import { TRPCReactProvider } from "~/trpc/react";

          <TRPCReactProvider>{children}</TRPCReactProvider>
        </AuthProvider>
      </body>
    </html>
  );
}

the AuthProvider

"use client";

import { SessionProvider } from "next-auth/react";
import { type ReactNode } from "react";

export const AuthProvider = ({ children }: { children: ReactNode }) => {
  return <SessionProvider>{children}</SessionProvider>;
};

"use client";

import { SessionProvider } from "next-auth/react";
import { type ReactNode } from "react";

export const AuthProvider = ({ children }: { children: ReactNode }) => {
  return <SessionProvider>{children}</SessionProvider>;
};

There's a few things you can check: 1 - Network issue: check if your deployment is in the same region as your database. When in dev mode, your client and server are the same, so, its your machine -> db -> your machine. When in prod, its your machine -> server > db -> server -> your machine. 2 - Execution issue: log the execution time of the login logic and check the log on the server. 3 - Build issue(?): Build your project locally and test the built version of it
