iPerf2 vs Tessabyte

iPerf2 measures network traffic performance, including throughput, latency, link capacity, and responsiveness. Testing uses a client to send traffic to a server. It can generate TCP and UDP traffic in one-way, bidirectional, full-duplex, and simultaneous multi-stream configurations. Measurements include one-way delay, round-trip time, jitter, packet loss, and throughput. It supports IPv4, IPv6, and multicast, including source-specific multicast joins, and reports can include enhanced metrics or use CSV format. The project manual describes an Android client with live meters for throughput, latency, and congestion signals. The manual also describes permit-key HMAC authentication using a timestamped HMAC-SHA256 value, with replay limited by a configurable time window. Its Professional feature set includes server access gating and remotely enabled server-side latency histograms. Measurements happen at socket-level reads and writes, so lower-level protocol-header overhead is excluded. iPerf2 and iPerf3 are separate implementations and do not interoperate. It runs on Android, Linux, macOS, and Windows, and can be self-hosted. Both listed editions are free.

Tessabyte measures performance on wired and wireless networks, including speed, packet loss, and jitter. Listed uses include Wi-Fi speed tests, network capacity tests, link quality analysis, stress tests, QoS assessment, and SLA verification. It tests across LAN and Wi-Fi using IPv4, IPv6, TCP, and UDP. Results can chart uplink and downlink speeds, packet loss, and jitter; users can customize payloads and generate reports. The software has client and server components, and multiple clients can connect to one server. The server component is free and can be installed on unlimited Windows, macOS, or Linux machines. Its evaluation version is fully functional for 30 days from first execution. Client licenses are one-time purchases: the 1-user license is $39 as a one-time purchase, and licenses are also listed for three, five, ten, and 25 users. Each Windows or macOS client user license allows installation on up to three personal machines, and one license is required per user. Purchases include technical support and software updates for one year; the license remains usable afterward, with upgrades available separately. Tessabyte is self-hosted, and its maker describes it as intended for professionals who have outgrown iPerf.
