How to Tune Nginx Kernel Parameters for Up to 10× Performance Boost

The article walks through a step‑by‑step Nginx performance tuning guide, covering worker_processes and worker_connections settings, Linux file‑descriptor limits, sysctl tweaks such as net.core.somaxconn and tcp_max_syn_backlog, explicit listen backlog, and zero‑copy sendfile with tcp_nopush/tcp_nodelay to dramatically increase throughput and lower CPU usage.

How I Cut API Response Time from 500 ms to 100 ms with Linux Tuning

This article recounts a two‑week Linux system tuning project that reduced a high‑traffic API’s P99 response time from over 500 ms to under 100 ms by systematically diagnosing bottlenecks, applying USE‑based analysis, and tuning kernel, network, file‑descriptor, memory, CPU, and I/O parameters.

Ctrip Mobile App Network Service Architecture and Performance Optimizations

This article details Ctrip's mobile app network service architecture, the rationale for using TCP over HTTP, and a series of channel governance and performance optimization techniques—including DNS bypass, socket connection pooling, weak‑network handling, data format improvements, retry mechanisms, Hybrid and overseas network enhancements—demonstrating how these measures raised service success rates above 99% and reduced latency.
