ModuleFederationPluginV2 causes extremely slow app startup on Android mid-range devices

[hndc9x]

Description

We are experiencing severe performance issues when using ModuleFederationPluginV2 in a React Native application with Re.Pack. The app startup time increases dramatically, especially on mid-range Android devices.

Environment

• Re.Pack version: 5.x (latest)
• React Native: 0.79+
• React: 19.x
• @module-federation/runtime: latest
• Platform: Android (iOS is less affected)
• Bundler: Rspack
• Device: Mid-range Android devices (e.g., Samsung A series, Xiaomi Redmi)

Problems Encountered

1. 🐢 Slow App Startup with ModuleFederationPluginV2

When using ModuleFederationPluginV2 with a large number of shared dependencies (15-30+ packages), the app startup time increases by 5-15+ seconds on mid-range Android devices.

Current config example:

new Repack.plugins.ModuleFederationPluginV2({
  name: "loyalty",
  dts: false,
  remotes: STANDALONE
    ? {
        InvoicePayment: `InvoicePayment@http://localhost:9000/${platform}/mf-manifest.json`,
        HelpCenter: `HelpCenter@http://localhost:9001/${platform}/mf-manifest.json`,
        TrackingOrder: `TrackingOrder@http://localhost:9002/${platform}/mf-manifest.json`,
        MWGShop: `MWGShop@http://localhost:9003/${platform}/mf-manifest.json`,
        UtilityServices: `UtilityServices@http://localhost:9004/${platform}/mf-manifest.json`,
        DMX: `DMX@http://localhost:9003/${platform}/mf-manifest.json`,
        PaymentGateway: `PaymentGateway@http://localhost:8000/${platform}/mf-manifest.json`,
      }
    : {
        InvoicePayment: `InvoicePayment@invoice.container.js.bundle`,
        HelpCenter: `HelpCenter@helpcenter.container.js.bundle`,
        TrackingOrder: `TrackingOrder@trackingorder.container.js.bundle`,
        MWGShop: `MWGShop@mwgshop.container.js.bundle`,
        UtilityServices: `UtilityServices@utility.container.js.bundle`,
        DMX: `DMX@dmx.container.js.bundle`,
        PaymentGateway: `PaymentGateway@paymentgateway.container.js.bundle`,
      },
  shared: {
    ...getSharedDependencies({ eager: true, bundle: false }),
    "react-native-webrtc": { singleton: true, eager: true },
  },
})
