iperf - Internet bandwidth measuring tool

Iperf is a modern alternative for measuring TCP and UDP bandwidth performance, allowing the tuning of various parameters
and characteristics.

Features:
      * Measure bandwidth, packet loss, delay jitter
      * Report MSS/MTU size and observed read sizes.
      * Support for TCP window size via socket buffers.
      * Multi-threaded. Client and server can have multiple simultaneous
          connections.
      * Client can create UDP streams of specified bandwidth.
      * Multicast and IPv6 capable.
      * Options can be specified with K (kilo-) and M (mega-) suffices.
      * Can run for specified time, rather than a set amount of data to transfer.
      * Picks the best units for the size of data being reported.
      * Server handles multiple connections.
      * Print periodic, intermediate bandwidth, jitter, and loss reports at
          specified intervals.
      * Server can be run as a daemon.
      * Use representative streams to test out how link layer compression affects your achievable bandwidth.
