This article outlines a step‑by‑step methodology for migrating existing services to a virtualized infrastructure, covering performance assessment, test‑environment validation, incremental rollout, full deployment, and constructing business pressure models, with special insights for game‑related workloads.
This article explains essential software performance testing concepts—including QPS/TPS, concurrency, response time, throughput calculations, think time, and how to estimate daily traffic using real‑world examples from e‑commerce platforms—providing formulas and practical guidance for engineers, administrators, and developers to assess and optimize system capacity.
This article explains the design and operation of journaling file systems, compares Ext3, ReiserFS, XFS, and JFS across their logging modes, internal structures, and performance results from Postmark and Bonnie++ tests, and offers practical conclusions for different workload scenarios.
This article reviews the evolution of big‑data management technologies, discusses the criteria for choosing appropriate big‑data benchmarks, compares existing benchmarks such as MapReduce tests, YCSB, BigBench and BigFrame, and provides an in‑depth analysis of the TPC‑DS benchmark and its certification status.
The article explains how TCPCopy can duplicate live TCP/UDP traffic for testing, describes the challenges of selective traffic copying, and details the design and implementation of DubboCopy—a Netty‑based proxy that lowers usage barriers, supports multi‑dimensional traffic selection, and monitors performance metrics with minimal resource overhead.
This article explains core performance testing concepts—including QPS, concurrency, response time, and throughput calculations—illustrates how to estimate system capacity, relate traffic metrics to daily PV, and outlines the perspectives of users, administrators, developers, and test engineers for evaluating software performance.
During the 11.11 shopping festival Xiaomi’s push service delivered 9.65 billion messages at an average of 670 k per minute, maintaining smooth operation without congestion through a multi‑datacenter, XMPP‑based architecture with Thrift serialization and extensive caching.
This guide walks you through enabling JMeter's English interface, configuring an HTTP Mirror Server, setting up distributed load testing, using debug logging, leveraging the search feature, and sharing variables between threads for more effective performance testing.
This article explains how to evaluate Hadoop workloads and select balanced hardware—covering storage, compute, network, and memory specifications for master and worker nodes—to build an efficient, cost‑effective Hadoop cluster.
This article examines Nginx's built‑in and third‑party load‑balancing algorithms—including weighted round robin, IP hash, fair, generic hash, and consistent hash—by dissecting their source code and presenting comparative performance tests across multiple scenarios to reveal their strengths and trade‑offs.
