We share insights on storage, computing, networking and explore leading industry technologies together.
This article reviews the challenges of web performance, analyzes HTTP/1.1, HTTP/2, TLS, and QUIC protocols, discusses optimization techniques such as TCP fast open, TLS false start, server push, preconnect, and presents practical recommendations from the 2017 ArchSummit presentation.
The article presents a comprehensive engineering solution that separates RSA operations, employs parallel and asynchronous processing, modifies OpenSSL and Nginx event handling, and adds symmetric‑encryption optimizations to boost SSL/TLS handshake throughput by over threefold while reducing CPU load.
The article explains how the Architecture Platform team builds a comprehensive, automated operations system—including CMDB, cost budgeting, monitoring, permission management, self‑service tools, and mobile access—to safely and efficiently manage tens of thousands of servers and massive storage services.
The article provides a comprehensive overview of TXSQL, Tencent's heavily customized MySQL kernel, detailing its motivations, version choices, performance improvements such as read‑view and redo‑log optimizations, added functionalities like multi‑mode operation and distributed locks, stability testing, financial‑grade features, benchmark results against official MySQL releases, upcoming support for MySQL 5.7, and future development directions.
The article details Tencent File System (TFS), describing its platform components, 3D indexing techniques, high‑performance key‑value storage (TSSD) with MHT, dual‑read and smooth scaling mechanisms, hybrid index storage, host‑level FTL, Append‑Only and erasure‑coding storage engines, and how these innovations deliver scalable, low‑cost, high‑performance data storage for massive workloads.
The article explains how WeChat C2C’s backend uses progressive JPEG encoding combined with a streaming transmission approach and a dynamically adjustable minimal transport size to reduce image delivery latency and improve user experience under varying network conditions.
