This article compares the effects of Concurrency (virtual user) mode and RPS (requests per second) mode in the Forcebot load‑testing platform on key service performance indicators such as TPS, TP99 and TP999, using a product‑query‑tag scenario to illustrate practical differences and recommendations.
This article examines the design of a self‑perception framework that places user perception at its core, detailing four critical stages—perception manifestation, demand, response, and feedback—and shows how AI‑enabled big‑data analysis can transform network operation management into a more intelligent, user‑centric process.
This article details iQIYI's implementation of Apache Kyuubi for Spark Thrift Server, covering the evolution from native Spark Thrift to Kyuubi 0.7 and 1.x, multi‑tenant architecture, tag‑based configurations, SQL auditing, lineage collection, service monitoring, small‑file and Z‑order optimizations, and a brief Q&A.
This article shares a step‑by‑step experience of refactoring a finance‑BFF aggregation service from tightly coupled synchronous calls to a loosely coupled, fully asynchronous architecture, covering problem background, redesign goals, implementation details, Hystrix integration, monitoring, and practical usage examples.
This article presents Qunar's comprehensive system slimming initiative, detailing the background of growing code bloat, the challenges of reducing millions of lines across thousands of services, the two‑phase plan for service and code pruning, the use of SA and other tooling to identify and safely delete unused resources, and the measurable outcomes such as nearly 50% code reduction, improved development speed, and future directions for further optimization.
This article explains common latency analysis techniques, details the principles and implementation of critical path tracing, and demonstrates its practical application in Baidu App's recommendation service to efficiently identify and reduce performance bottlenecks in complex distributed architectures.
Baidu's Comment Middle Platform evolved from a single service into a robust middleware that delivers stable, high‑performance comment functionality across more than twenty products, handling hundreds of millions of daily requests with 99.995% SLA through graph‑based scheduling, tiered caching, and scalable sorting mechanisms.
This article details a large‑scale C10K performance test of Dubbo, analyzes why service calls time out under thousands of concurrent consumers, identifies heartbeat‑induced Netty thread saturation and TCP full‑connection‑queue overflow as root causes, and presents concrete optimizations that dramatically improve latency and stability.
This case study details how 58.com acquired Youxin Auction, identified service, cost, and efficiency pain points, and redesigned the mobile auction platform with systematic thinking, visual innovation, consistent interaction, and information restructuring to improve dealer trust and transaction volume.
