📰 Dev.to · Viktor Logvinov
Learn how to mitigate excessive memory usage caused by Go Runtime's persistent 128MB heap arenas in CGO/Purego calls
Action Steps
- Identify memory usage patterns in your Go application using tools like pprof or memprof
- Configure your Go application to use a smaller heap arena size using the GOGC environment variable
- Implement manual memory management using Go's runtime/debug package to free unused memory
- Use the runtime/malloc package to track and optimize memory allocation
- Test and profile your application to ensure the solution is effective
