In a recent project, we encountered a tricky performance issue: the system would experience periodic latency spikes under high concurrency. After in-depth analysis, we found that the root cause was the garbage collection mechanism. Today I want to share a deep dive into memory management and how to avoid performance traps caused by GC. Modern web applications face several core challenges in memory management: Memory leaks are one of the most common performance issues in web applications. I've seen too many cases where systems crashed due to memory leaks. Garbage collection pauses directly lead to increased request latency, which is unacceptable in latency-sensitive applications. Frequent memory allocation and deallocation lead to memory fragmentation, reducing memory usage efficiency. I designed a comprehensive memory usage efficiency test, and the results were shocking: What impressed me most about the Hyperlane framework is its zero-garbage design. Through careful memory management, it almost completely avoids garbage generation. Object Pool Technology Stack Allocation Optimization For small objects, the Hyperlane framework prioritizes stack allocation: The Hyperlane framework adopts an aggressive memory pre-allocation strategy: Memory layout has an important impact on cache hit rate: Node.js's memory management issues have caused me a lot of trouble: Go's memory management is relatively better, but there's still room for improvement: Disadvantage Analysis: Rust's memory management has shown me the potential of system-level performance optimization: In our e-commerce system, I implemented the following memory optimization measures: Object Pool Application Memory Pre-allocation Payment systems have the strictest requirements for memory management: Memory Pool Management Future memory management will utilize more hardware features: Machine Learning Optimization Through this in-depth analysis of memory management, I have deeply realized the huge differences in memory management among different frameworks. The zero-garbage design of the Hyperlane framework is indeed impressive. Through technologies like object pools and memory pre-allocation, it almost completely avoids garbage collection issues. Rust's ownership system provides memory safety guarantees, while Go's GC mechanism, although convenient, still has room for improvement in latency-sensitive applications. Memory management is the core of web application performance optimization. Choosing the right framework and optimization strategy has a decisive impact on system performance. I hope my analysis can help everyone make better decisions in memory management.
