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 compares the concurrency (virtual user) mode and the RPS (requests per second) mode of the Forcebot load‑testing platform, showing how each impacts TPS, TP99, and TP999 metrics through a product‑query tag case study, and explains when to apply each mode for optimal service performance.
This article explains Linux network‑stack enhancements—RSS, RPS, RFS, accelerated RFS, and XPS—detailing their purpose, configuration steps, and recommended settings to improve parallelism and latency on multi‑CPU systems.
As AI workloads push intelligent compute power growth beyond 50% CAGR, data‑center networks face massive parallel paths, making traditional ECMP load‑balancing insufficient and causing severe congestion, while newer granular schemes such as packet‑spraying, flowlet, and cell‑based balancing offer higher bandwidth utilization and fairness.
This article details Tencent's cloud load‑testing approach for handling massive traffic spikes during Chinese New Year, covering background challenges, model selection, script authoring options, data construction, report analysis, and real‑world case studies that demonstrate capacity planning and performance optimization.
This article explains the limitations of single‑connection request handling, demonstrates the performance benefits of multiplexing, and details a .NET Core test that reaches a million requests per second with low latency using Protobuf messages and BeetleX integration.
The article walks through a real‑world investigation of an Nginx HTTP forward proxy on an Alibaba Cloud server that stops accepting new connections after a while, detailing hypothesis testing, strace analysis, fastsocket feature toggles, accept_mutex behavior, and the final fix by adjusting the NIC's RPS settings.
