Commands Reference, Volume 5
sprayd Daemon
Purpose
Receives packets sent by the spray command.
Syntax
/usr/lib/netsvc/spray/rpc.sprayd
Description
The rpc.sprayd daemon is a server
that records the packets sent by the spray command. The rpc.sprayd daemon is normally
started by the inetd daemon.
UDP Performance
User Datagram Protocol (UDP) performance with the spray command and the rpc.sprayd daemon
can be affected by the following factors:
- How memory buffers (mbufs) are tuned for
system configuration.
- The incoming burst rate (that is, interframe
gap) of UDP packets for the spray command.
- Other system activity. Since the rpc.sprayd daemon runs as a normal user process, other activity (such
as the init process, or the syncd
daemon) can affect the operation of the rpc.sprayd daemon.
- Priority of the rpc.sprayd daemon process. The rpc.sprayd daemon has a floating
process priority that is calculated dynamically.
- The size of the receive socket buffer used
by the rpc.sprayd daemon. Because various implementations
use different socket buffer sizes, measuring UDP performance with the spray command and the rpc.sprayd daemon
is difficult and inconclusive.
