Code Example

You got us all into using next js, and now it is crushing and slow - impossible to work with. especially with a debugger.

Please get yourself together - fix it, or move back to what ever was working good on v14 - it is absolutely outrageous that a production level product degraded like this when thousand of company are depended on it

TL;DR

Revert to the previous version (v14) or investigate optimization techniques for Next.js to improve performance.

Guidance

  • Investigate the specific performance issues with Next.js by profiling the application and identifying bottlenecks.
  • Consider optimizing server-side rendering, code splitting, or image compression to improve performance.
  • Review the debugger configuration to ensure it's not causing unnecessary overhead.
  • Check for any known issues or updates in the Next.js documentation that may address the performance degradation.

Example

No specific code example can be provided without more details on the implementation.

Notes

The issue lacks specific technical details, making it challenging to provide a precise solution. The performance degradation could be caused by various factors, including but not limited to, incorrect Next.js configuration, inefficient code, or inadequate hardware resources.

Recommendation

Apply workaround: Revert to the previous version (v14) until the performance issues with Next.js are resolved, as it is reported to have worked well in the past.
