Go 1.5 Garbage Collection Performance with Large RAM
Can Go's Recent GC Improvements Handle Terabytes of RAM?
Go's garbage collector (GC) has undergone significant updates in version 1.5, raising questions about whether it can now support large amounts of RAM. While the GC pauses have been reduced, it is essential to understand how the GC workload impacts performance when considering terabyte-scale RAM usage.
Key Points
GC Performance Observations
The 1.5 GC aims to reduce pauses by working in the background. While it has markedly reduced pause times for small and medium heaps, GC workload remains a significant factor. Production applications have reported dramatic reductions in pause times, ranging from milliseconds to hundreds of milliseconds.
Conclusion
While Go's GC performance has improved, using multiple processes or optimizing data structures is recommended for applications requiring terabytes of RAM. Careful design, prototyping, and testing are essential to avoid memory issues in such scenarios.
