Describe a scenario where you used a profiling tool to identify and fix a performance bottleneck in a Go program.
- The application was slow due to frequent database queries.
- The application had too many comments in the code.
- The code was indented incorrectly.
- The application used a popular framework.
In a real-world scenario, the Go application's performance was hindered by frequent database queries. Using a profiling tool, it was discovered that certain database queries were inefficient. The queries were optimized, and the application's response time significantly improved. Profiling tools help pinpoint performance bottlenecks by showing which functions consume the most time or resources, enabling developers to focus their optimization efforts effectively. The other options are unrelated to profiling or performance optimization.
