This article explains a reproducible Linux network performance assessment covering latency, throughput, bandwidth, and packet loss, introduces built‑in and benchmark tools such as ping, ss, nstat, ethtool, iperf3, netperf and wrk, and provides a step‑by‑step workflow to generate a complete evaluation report.
Learn a comprehensive, step‑by‑step guide to testing network performance on Linux, covering beginner commands like ping, download speed checks with curl/wget, advanced utilities such as speedtest‑cli, iperf3, iftop, nload, nethogs, bmon and vnstat, plus installation tips, usage examples, and practical advice for different scenarios.
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.
This article introduces the most important Linux network testing utilities—covering basic connectivity, routing analysis, DNS resolution, port monitoring, bandwidth measurement, and packet capture—providing a comprehensive guide that helps operations engineers diagnose and resolve network issues ten times faster.
This guide explains the concepts of network bandwidth, shows how to check physical and virtual NIC speeds on Linux using ethtool, dmesg, and mii‑tool, demonstrates real‑world throughput testing with iperf3, and provides tips for identifying network bottlenecks.
This article presents a systematic performance test of the DTLE data replication tool, using sysbench, tc, and iperf3 to simulate different network latency and bandwidth scenarios, and compares DTLE's replication delay and bandwidth usage against native MySQL replication across three test cases.
