A sub-millisecond GC for .NET?

a year ago

Introduction of Satori, an experimental Garbage Collector (GC) for .NET, showing significant performance improvements.
Key improvements include 50x better median pause time, >100x better 99th percentile pause times, and 3x better heap size.
Garbage collection is crucial for memory management in high-level languages like C#/.NET, Java, and Go, but not in lower-level languages like Rust and C/C++.
GCs can cause disruptive 'stop the world' pauses, affecting application performance, especially in high-throughput scenarios.
Historical evolution of .NET GC from Workstation GC to Server GC, with innovations like Concurrent and Background GC.
Comparison with other ecosystems, notably Go's GC, which offers extremely low pause times, sparking envy among .NET developers.
Satori GC, developed by Vladimir Sadov, promises sub-millisecond pause times, making it competitive with the best in the industry.
Performance benchmarks show Satori drastically reduces GC time percentage and improves allocation rates and pause times across percentiles.
Instructions provided to try Satori include building apps targeting .NET 8.0, publishing in self-contained mode, and replacing specific DLLs.
Encouragement for developers to test Satori in their workloads and provide feedback to influence its development and prioritization.
