 To measure network performance, consider use of a

-script such as
-* [network-stream-pairs.sh](https://github.com/bengland2/parallel-libgfapi/blob/master/netperf-stream-pairs.sh) - sets up unidirectional TCP streams between pairs of hosts
-* [network-rpc-pairs.sh](https://github.com/bengland2/parallel-libgfapi/blob/master/netperf-rpc-pairs.sh) - sets up request-response flows between pairs of hosts

+script.
 
 The purpose of these two tools is to characterize the capacity of your entire network infrastructure to support the desired level of traffic induced by distributed storage, using multiple network connections in parallel.   The latter script is probably the most realistic network workload for distributed storage.
