hperf is a tool for active measurements of the maximum achievable bandwidth between N peers, measuring RX/TX bandwidth for each peers.

Download Binary Releases for various platforms.

• Calculate baseline RX/TX
• Debug TOR Switch bottlenecks

./hperf IP1 IP2 IP3 ...
...
Bandwidth: 1.2 GB/s RX | 1.0 GB/s TX
Bandwidth: 1.2 GB/s RX | 1.1 GB/s TX
Bandwidth: 1.2 GB/s RX | 990 MB/s TX
Bandwidth: 1.2 GB/s RX | 944 MB/s TX

on all the servers IP1 IP2 IP3 ... respectively.

Default ports are 9999 and 10000 make sure your firewalls allow these ports. You may optionally configure ./hperf to use custom ports as well, for example setting port 5001 would require opening up port 5002 as well.
