NAME
       spray - spray packets

SYNOPSIS
       count] delay] length] nettype] host

DESCRIPTION
       sends  a one-way stream of packets to host using RPC, then reports how many were received by host and what the transfer rate was.  The host
       name can be either a name or an internet address.

       is not useful as a networking benchmark, as it uses unreliable connectionless transports, UDP, for example.  can report a large	number	of
       packets	dropped when the drops were caused by sending packets faster than they can be buffered locally, that is, before the packets get to
       the network medium.

   Options
       recognizes the following options and command-line arguments:

	      Specify how many packets to send.
			     The default value of count is the number of packets required to make the total stream size 100000 bytes.

	      Specify how many microseconds to pause between sending each packet.
			     The default is 0.

	      Specify the number of bytes in the Ethernet packet that holds the RPC
			     call message.  Since the data is encoded using XDR, and XDR only deals with 32 bit  quantities,  not  all	values	of
			     length  are  possible,  and  rounds up to the nearest possible value.  When length is greater than 1514, then the RPC
			     call can no longer be encapsulated in one Ethernet packet.  In that case, the length field no  longer  has  a  simple
			     correspondence  to  the  Ethernet	packet size.  The default value of length is 86 bytes, the size of the RPC and UDP
			     headers.

	      Specify class of transports.
			     Defaults to See rpc(3N) for a description of supported classes.
