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.
