The netperf cluster provides a multi-node, SMP-capable, network functionality and performance test capability for the FreeBSD Project, supporting a variety of on-going sub-projects including the netperf project, Dingo project, and on-going work on high performance threading. The cluster is available on a check out basis for developers, who must request accounts be created by contacting one of the netperf cluster admins.


The netperf cluster was made possible through the generous donation of a number of organizations, including:

Donations to support the netperf cluster have an immediate and substantial impact on the success of a number of on-going performance projects, providing access to high-end hardware to a large number of developers. If you or your company are interested in helping to support continued development of the netperf cluster as a resource for FreeBSD development, please contact the netperf cluster admins.

Netperf Cluster Admins

The FreeBSD netperf cluster is managed by a small team of developer/administrators to support SMP development and performance testing on high-end hardware. If you have any questions, including questions about access to the cluster as a developer, or about possible future donations of testing hardware, please feel free to contact the following:

Netperf Cluster Resources

The Netperf cluster consists of several systems interconnected using a management network, as well as individual back-to-back gigabit ethernet links for a test network. The following systems are available as testing resources on a check-out basis:

The current serial port and network configuration of test systems, as well as password information, can be found in /etc/motd on zoo. We are currently interested in adding amd64 and em64t hardware to the cluster.

Netperf Cluster Procedures

As the netperf cluster is a centrally managed and shared resource, understanding and consistent following of its procedures is important. In particular, following of the procedures makes it easier for developers to have reasonable expectations about the configuration of systems in the cluster, as well as to avoid treading on each others toes.

Current Configuration Notes and News

A few hopefully up-to-date configuration notes that may be relevant to users of the netperf cluster:


Currently, no automated reservation system is in place for the netperf cluster, but we hope to introduce some system for reservation shortly. In the meantime, the following standing reservations are in place for the netperf cluster:
