Spread Performance Test Client

## NAME

spflooder - Spread Performance Test Client

## SYNOPSIS

**spflooder \[-u** *connection\_name***\] \[-s** *spread\_address***\] \[-m** *num\_messages***\] \[-b** *bytes\_per\_message***\] \[-ro\] \[-wo\]**

## DESCRIPTION

**spflooder** is a Spread client program that can flood messages and measure the time required to send a certain number of messages. This can be used to  test the performance of Spread and the machines it runs on. By default it trys to connect to a Spread daemon running on port 4803 of the local machine.

## OPTIONS

- \-u connection\_name

  The name this connection to the daemon will use to uniquely identify itself.

- \-s spread address

  The port number, or port number and host to which the spuser  program should connect in order to reach a Spread daemon.

- \-m num messages

  The number of messages to flood.

- \-b num bytes

  The size of each message to send in bytes.

- \-ro

  This flooder process will only receive messages sent by other flooders. It will not send any messages.

- \-wo

  This flooder process will only send messages to other flooders. It will not receive any messages.

## BUGS

Some limitations on message size and number of groups are hardcoded into spflooder. Some changes to the code may be necessary to get maximum performance in large Spread configuarations.
