This guide walks you through a complete set of Linux network‑speed testing utilities—from the built‑in ping command to curl/wget downloads, Speedtest‑CLI, iperf3, iftop, nload, nethogs, bmon and vnstat—explaining installation, core metrics, usage examples, and practical tips for accurate measurement and troubleshooting.
VectorChord‑BM25 is a PostgreSQL extension that adds native BM25 ranking and tokenization, delivering up to three‑fold query‑per‑second improvements over ElasticSearch while maintaining comparable relevance scores, and includes detailed installation, usage examples, and performance analysis.
Using AI to assist domain-driven design, this case study details how a monolithic Taobao service-package system was analyzed, restructured, and refactored, reducing development effort from 5-8 person-days per package to configuration-based implementation while eliminating duplicated code and improving modularity, testability, and scalability.
This article explains how to determine whether a given unsigned integer belongs to a set of 4 billion distinct numbers within a 1 GB memory limit, comparing a bitmap approach with a Bloom filter, providing detailed implementation steps and C++ code examples for both methods.
When a ClickHouse cluster needed to be decommissioned, the author evaluated three migration approaches—using Doris' ClickHouse catalog, exporting to files with Broker/Stream Load, and leveraging Spark—to move roughly 100 billion rows to Doris, comparing their complexity, reliability, and performance.
This article explains the reasons behind MySQL IN‑clause parameter limits, the performance impact of large IN lists, and provides practical optimization techniques such as splitting queries in application code and using temporary tables with EXISTS to improve efficiency.
A client reported sudden Oracle database slowdown, prompting a post‑mortem analysis using AWR and TFA data that revealed GC bottlenecks, RAC heartbeat packet loss, and an intermittent storage link failure, ultimately resolved by disabling the faulty port and restarting the affected node.
This article translates and expands Anton Putra's benchmark, detailing how to deploy Nginx and Envoy on AWS with Terraform and Ansible, run HTTP, HTTPS, and gRPC load tests using K6, measure CPU and latency with Prometheus, and compare the resulting throughput and stability of both proxies.
With MinIO entering maintenance mode, this article evaluates open‑source S3‑compatible alternatives—Ceph, SeaweedFS, Garage, and RustFS—detailing their strengths, limitations, security concerns, and practical deployment tips, while concluding that none yet offers a perfect drop‑in replacement.
