You have been tasked with improving the performance of a Go web application. Describe the steps you would take to profile and optimize the application.
- Use a profiler to identify bottlenecks, optimize the critical path, and test performance.
- Rewrite the entire application codebase.
- Increase server resources like CPU and RAM.
- Disable logging to improve performance.
Profiling and optimizing a Go web application involves several steps. Using a profiler (like pprof) is crucial to identify performance bottlenecks. Once identified, the critical path can be optimized. It's important to follow up with performance testing to validate improvements. Rewriting the entire codebase is an extreme measure and not a recommended step for optimization. Increasing server resources or disabling logging alone may not address the root causes of performance issues.
