To find code performance issues in production, use monitoring tools and profiling techniques.

Use monitoring tools like New Relic, AppDynamics, or Datadog to track performance metrics and identify bottlenecks.
Use profiling techniques like CPU profiling, memory profiling, and network profiling to pinpoint specific areas of the code that are causing performance issues.
Analyze logs and error messages to identify patterns and potential performance issues.
Perform load testing and stress testing to simulate real-world usage and identify performance issues before they occur in production.
Collaborate with other developers and stakeholders to identify potential performance issues and implement solutions.
Continuously monitor and optimize code performance to ensure optimal user experience and minimize downtime.
