Web Application Stress Tool only supports stress against one
server or DNS name at a time.
To use authentication, you must add users with valid user
names and passwords.
To record, you will need to modify your browser settings if
using a browser other than, or prior to, IE 5.0. See online
help for more information.
Webtool respects the "user-agent: stress-agent" directive in
the ROBOTS.TXT file on a web server and will not start a
stress test against a server or domain that contains this
file with this directive. This file should be located in
the root directory of your web site

In general, you should NOT install the WebTool service on
the web server you are testing since this may interfere with
your results.

The Web Application Stress Tool object model can be used to
start, stop, and configure a test run.  However, this feature
cannot be used to modify a running test in this version of
the tool.

Web Application Stress Tool is year 2000 compliant.

IMPORTANT: Start your test with a small number of
Concurrent Connections and then work your way up to the
desired stress level slowly, watching the processor
utilization on the clients and web server. If the
processor utilization is consistently above 90% on one or
more machines, the test is probably invalid. If this
occurs, decrease the number of concurrent connections or
add more client machines to handle the desired stress load.

On-line help contains a discussion of performance testing
techniques.

Although there is no hard limit on the number of script
items you can have in one script, the most practical limit
is 3000 script items. Beyond that you will find that it
takes an inordinately long time to start and stop tests.
