Internet Protocol 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.
