[punkpeye]

[PLUGIN_TIMINGS] Warning: Your build spent significant time in plugins. Here is a breakdown:
  - react-router:virtual-modules (64%)
  - vite:worker (8%)
  - import-meta-env-ssr (7%)
  - babel-plugin (5%)
  - base64-loader (4%)
See https://rolldown.rs/options/checks#plugintimings for more details.

Recently adopted rolldown and it sped up build times significantly.

But it highlights react-router:virtual-modules as the slowest plugin, account for 64% of total build time.

Has any work gone into profiling the plugin to determine what can be optimized
