Its README positions Flowgrind as a distributed TCP measurement tool, similar in broad purpose to iperf and netperf but with a controller and daemon architecture. Through the 2010s, official release notes added traffic-generation features, libpcap dumping, FreeBSD support, IPv6 support, GPLv3 licensing, Mac OS X support, UUID-based daemon identification, and compatibility fixes. The project later moved its website to flowgrind.github.io. ### Adoption history Flowgrind has been packaged as a niche but durable network-measurement utility for operators and researchers who need controlled TCP experiments across multiple endpoints. Its official README emphasizes third-party tests, parallel flows, transport-layer metrics, and optional separation of control and test traffic. ### How it is used A normal test starts flowgrindd on endpoint machines and runs flowgrind from a controller host with source and destination hosts passed through -H. The controller can schedule multiple flows, collect periodic results, and display measurements from the daemons. Flowgrind measures throughput, interarrival time, round-trip time, block counts, transactions per second, and, where supported by the OS, TCP stack details such as congestion window and slow-start threshold. ### Why package nerds care Flowgrind is package-interesting because it sits beside iperf and netperf but exposes a more distributed RPC-style model. Packaging it means shipping both the controller and daemon binaries plus native dependencies such as xmlrpc-c, uuid, libpcap, and GSL. ### Timeline - 2006: Flowgrind 0.1 initial release. - 2010: Flowgrind 0.5 adds libpcap support and advanced traffic-generation dependencies. - 2013: Flowgrind 0.6 adds full IPv6 support for control and test connections. - 2014: Flowgrind 0.7.1 changes license to GPLv3; 0.7.5 re-adds Mac OS X support. - 2016: Flowgrind 0.8.0 introduces UUID daemon identification and many bug fixes. - 2021: Flowgrind 0.8.1 moves the website to flowgrind.github.io; 0.8.2 updates packaging and version fixes. ### Related projects - The official README explicitly names iperf3 and netperf as related TCP measurement tools. ### Sources - - - - - ## Security Notes narrow executable package without higher-risk signals. - **Geiger risk:** green / low - narrow executable package without higher-risk signals ## Source Database Details - **Source Database:** Homebrew formula API - **Tap:** homebrew/core - **Full Name:** flowgrind - **Version Scheme:** 0 - **Revision:** 4 - **Head Version:** HEAD - **Bottle Stable Root URL:** - **Deprecated:** no - **Disabled:** no - **Keg Only:** no - **URL Keys:** head, stable ## Other Package-Manager Records - Debian apt - flowgrind - 0.8.2-2+b4: normalized package name match | Debian stable package indexes: flowgrind from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Distributed network performance measurement tool | https://flowgrind.github.io - Debian apt - flowgrind-dbg - 0.8.2-2+b4: normalized package name match | Debian stable package indexes: flowgrind-dbg from https://deb.debian.org/debian/dists/stable/main/binary-amd64/Packages.xz | Debugging version of flowgrind | https://flowgrind.github.io - Ubuntu apt - flowgrind - 0.8.2-2build3: normalized package name match | Ubuntu 24.04 LTS package indexes: flowgrind from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Distributed network performance measurement tool | https://flowgrind.github.io - Ubuntu apt - flowgrind-dbg - 0.8.2-2build3: normalized package name match | Ubuntu 24.04 LTS package indexes: flowgrind-dbg from https://archive.ubuntu.com/ubuntu/dists/noble/universe/binary-amd64/Packages.gz | Debugging version of flowgrind | https://flowgrind.github.io - zypper - flowgrind - 0.8.2-2.1: normalized package name match | openSUSE Tumbleweed package metadata: flowgrind from https://download.opensuse.org/tumbleweed/repo/oss/repodata/be8d3611d25469107f32075a1697e69ec57a2b850b42348a658cc671ad5ec2b50760d02c3e59524d50da9a11d5be799bdaffba2e166e8ca8858512e3c0bd665d-primary.xml.zst | Network performance measurement | https://flowgrind.github.io ## Related links - [Source-control packages](https://www.automicvault.com/pkg/source-control-tools/) - Belongs to a source-control command family. - [Terminal utility packages](https://www.automicvault.com/pkg/terminal-utilities/) - Matched terminal and command-line workflow metadata. - [Developer build packages](https://www.automicvault.com/pkg/developer-build-tools/) - Matched build, compiler, generator, or developer workflow metadata. - [Networking and protocol packages](https://www.automicvault.com/pkg/networking-protocol-tools/) - Matched network, protocol, or remote-service metadata. - [gsl](https://www.automicvault.com/pkg/brew/gsl/) - Runtime dependency declared by Homebrew. - [xmlrpc-c](https://www.automicvault.com/pkg/brew/xmlrpc-c/) - Runtime dependency declared by Homebrew. - [nuttcp](https://www.automicvault.com/pkg/brew/nuttcp/) - Shares av.db curated category or tags: cli, networking, performance-testing, tcp. - [iperf](https://www.automicvault.com/pkg/brew/iperf/) - Shares av.db curated category or tags: cli, networking, performance-testing, tcp. - [iperf3](https://www.automicvault.com/pkg/brew/iperf3/) - Shares av.db curated category or tags: cli, networking, performance-testing, tcp. - [dnsperf](https://www.automicvault.com/pkg/brew/dnsperf/) - Shares av.db curated category or tags: benchmarking, cli, networking, performance-testing. - [dnspyre](https://www.automicvault.com/pkg/brew/dnspyre/) - Shares av.db curated category or tags: benchmarking, cli, networking, performance-testing. - [owamp](https://www.automicvault.com/pkg/brew/owamp/) - Shares av.db curated category or tags: cli, network-measurement, networking, performance-testing. - [dish](https://www.automicvault.com/pkg/brew/dish/) - Shares av.db curated category or tags: cli, networking, tcp. - [dns2tcp](https://www.automicvault.com/pkg/brew/dns2tcp/) - Shares av.db curated category or tags: cli, networking, tcp. ## Combined YAML source View the package source record on GitHub.
