varnetload - tool to create reproducable network traffic
SYNOPSIS
varnetload [-d delay] [-t time to run] [-u url]
DESCRIPTION
varnetload is a simple python script to create reproducable sustained network traffic.

any other kind of file) to the HTTP server. Use the -u option of the script to point to that URL. Play with the delay option to vary the
load put on your network.
delay Sets delay between individual downloads in miliseconds. Default value is 1000. But you my find values range from 0 to 500 more use-
ful.
time to run
Sets total run time in seconds. Default value is 60.
url Sets downloaded resource. Default is http://myhost.mydomain/index.html.
