Hey, I’ll need a bit more info to figure this out:

  • What exactly got slower, the editor itself like UI lag, switching files, or the Next.js dev server taking longer to compile or render pages?
  • Your Cursor version from Help > About
  • Can you try starting Cursor with extensions disabled from the command line: cursor --disable-extensions Did it get faster?
  • While it’s happening, open Task Manager and share a screenshot if you see high CPU or RAM usage from Cursor processes

If the issue is only the Next.js dev server compiling pages, a Cursor update usually won’t affect that. It’s worth checking your Node.js version and your Next.js version. But if the IDE itself is slow, we can dig further.
