Win32 TCP/IP Performance Test Tool
==================================
                                               LSS 5.0(0), August 1996
                                               -----------------------

W32PERF is a simple utility  for testing the performance of network
components  connecting  computers supporting the  Win32  API  (i.e. 
Windows NT and Windows 95).

There are four versions of the W32PERF.EXE executable; one for each
of the  processor types supported  by  Windows NT.  Use the version 
appropriate for your platform.

W32PERF  is  an  ordinary  Win32  application  program  that  tests
performance by sending data over a TCP/IP  connection.  This  means 
that W32PERF can  be  used  to  test  any combination of networking 
hardware.


Using W32PERF
-------------

W32PERF requires one computer to be used as a server and one or more
other computers to be used as clients. You must first  start W32PERF
on the server with the command:

    w32perf
    
If  you  are  only using one client then you must next start W32PERF
on the client with the command:

    w32perf -c a.b.c.d
    
where a.b.c.d is the IP address of the server.  If  multiple clients
are being used, then on all but the last client  start  W32PERF with
the command:

    w32perf -c a.b.c.d -n
    
    
and on the last client start W32PERF with the command:

    w32perf -c a.b.c.d
   
The -n parameter tells W32PERF that this is not  the  last  client to
join in on the test.

W32PERF will now run for around a minute.  At the end of the test run
the server W32PERF will display a table of results showing  the  read
and write performance of the  network.  If multiple clients are being
used  then  results  for each client will be displayed along with the 
aggregate performance.


Controlling the tests
---------------------

There are several extra  parameters  listed  below  that  allow  some
control over how W32PERF carries out its performance tests.

    -c server: Means this computer is a client and 'server' is the IP 
               address of the server.
        
    -b base:   Sets  the  smallest  transfer  size to 'base' (default 
               131072).
        
    -l limit:  Sets  the  largest  transfer  size to 'limit' (default 
               131072).
               
    -i inc:    Sets the transfer size increment to 'inc' (default 256).
               The range for 'base', 'limit' and 'inc' is 256 to 131072
               and the value must be a multiple of 256.
               
    -v level:  Sets the verbocity level to 'level'
               (range 0 - 4, default 2).\n")
               
    -r:        Means only run the client read tests.
    
    -w:        Means only run the client write tests.
    
    -n:        Means that this is not the last client to
               take part in the test.
               
    -z nnn:    Use nnn * 25 MBytes of data for each test cycle 
               (range 1 - 80, default 1).
