netperf is a network performance measurement tool
It relies on two programs running on separate computers:
a netserver that listens for commands from ...
a netperf client that sends those commands at the user's direction.
The netperf client's commands tell netserver to send or receive streams of data
between the two devices and then measures the data transfer rates between them.
Bandwidth for the netperf-*.bufferbloat.net servers is donated by individual users and is not sponsored by any big-pocket company, so please use deliberately.
This server is open to individuals for occasional network performance tests
and network researchers who need a stable system for testing network protocols and implementations.
We reserve the right to block access if we detect sustained over-use.
If you would like to use this server frequently, please contact us through the About page.
Recent netserver activity
This server hosts a netserver that is publicly accessible.
It's open to anyone to use, so it may be heavily loaded from time to time.
It also has limited bandwidth to certain parts of the Internet
(see the About page for details.)
This page shows the current and recent load.
The stats below show the netserver process activity, summarized from the creation dates of the 'netserver.debug*' files in /tmp.
