                       Siege README

WHAT IS IT?
-----------
Siege is an open source regression  test and  benchmark utility. 
It can stress test a single URL  with a user  defined  number of 
simulated  users, or  it can  read  many  URLs into  memory  and 
stress  them  simultaneously.  The  program  reports  the  total 
number  of  hits  recorded,  bytes  transferred,  response time, 
concurrency, and return status.  Siege supports HTTP/1.0 and 1.1 
protocols, the  GET and POST  directives,  cookies,  transaction 
logging, and basic authentication. Its features are configurable 
on a per user basis.

Most features  are configurable  with command line options which
also include  default values  to  minimize the complexity of the 
program's invocation.  Siege allows  you  to stress a web server 
with  n number of users  t number  of  times,  where n and t are 
defined  by the user.  It records the duration  time of the test
as  well as the duration of each single transaction.  It reports
the number  of  transactions,  elapsed time,  bytes transferred,
response time,  transaction rate,  concurrency and the number of
times the server responded OK, that is status code 200. 

Siege  was  designed  and  implemented  by Jeffrey Fulmer in his 
position as  Webmaster  for Armstrong World Industries.  It  was
modeled  in  part after Lincoln Stein's torture.pl and it's data
reporting  is  almost  identical.  But torture.pl does not allow 
one to stress many  URLs simultaneously;  out of that need siege
was born....

When a HTTP server is being hit by the program, it is said to be 
"under siege."


WHY DO I NEED IT?
-----------------
Siege was written for both web developers and web systems admin-
istrators.  It  allows  those individuals to test their programs 
and  their systems under duress.  As a web professional, you are 
responsible  for the intregrity of your product, yet you have no 
control  over who  accesses it.  Traffic spikes can occur at any 
moment.  How do you know if you're prepared?

Siege  will  allow you to place those programs  under duress, to 
allow  you  to  better  understand  the  load that they can with 
stand.  You'll sleep  better knowing your site can withstand the 
weight  of  400 simultaneous transactions if your site currently
peaks at 250.

A transaction  is  characterized  by the server opening a socket
for the client,  handling a request,  serving data over the wire 
and closing the socket upon completion.  It is important to note 
that  HUMAN  internet  users  take time to digest the data which
comes back to them.  Siege users do not.  In practice I've found
that 400  simultaneous  siege users  translates to at least five 
times that amount in real internet  sessions.  This is why siege
allows you to set a delay ( --delay=NUM ).  When set, each siege
user sleeps for a  random  number  of seconds between 1 and NUM.
Through your  server logs you should be  able to get the average
amount of time spent on a page.  It is  recommended that you use 
that number for your delay when simulating internet activity.
