The article discusses the importance of optimizing the performance of operating systems, particularly focusing on locklessly sharing data between threads using methods such as RCU (Read, Copy, Update). The author explains the concept of RCU in detail, highlighting its wait-free nature but cautioning against potential memory leaks if not implemented correctly. The article challenges common misconceptions about garbage collection (GC) being slower than manual memory management, emphasizing that modern GC offers optimizations that traditional methods cannot match. The author concludes by advocating for the use of GC as a valuable tool in software development, especially in high-performance systems where latency is critical.
