Increse user load

[Henrik Ridder <he...@partitur.se>]

Hi

I woundering how you increse the user load. I have a auth-file with a
couple of users but it seems that
jmeter is only using the first one in the file.

Mybe I'am doing something wrong.
I have the lastest CVS version of jmeter compiled with jdk1.2.2 Freebsd

Thanks

Henrik

That's what I thought to. But thanks for clearing that up. Are there
any plans for that in the future?

Well It's just as you explained (see bellow). We have a web-base
application (a e-learning application) that we want to investigate
how many user you can have at the same time to find the bottle-necks.
But to make it real we want to use different user and
not the same over and over again. But for now it's ok.

I can use the same user or I can add new threads.

Re: Increse user load

As far as I know, JMeter does not really simulate
multiple users.  Instead, it simulates multiple
instances (threads) of a single "user".  I know it
sounds a little confusing, but let me describe it
better with a concrete example.  [If any of this is
incorrect, please correct me.  We really need to
clearly describe this in the user's guide.]

The HTTP Authorization table can contain many entries.
However, JMeter does not randomly select a particular
user to login as.  Instead, JMeter looks at the Base
URL you provide and the URL that you are requesting
and.  If there is a match, it will send a single (the
first?) match that it finds. So, you could have five
users with the same Base URL (for example, "/login"),
but only one of these users will be chosen and it will
be the same user every time.

I can investigate it further.  Henrik, if you could
provide us with an example of why you would like
multiple users, then that would help us.

I can think of an example of where this could be a
problem.  Let's say that you have a system and you
want to simulate 100 users.  When you run JMeter, you
will get 100 logins for the same user ID (defined in
the Authorization table).  The application may not
allow a user to be logged in multiple times.

I think we have a similar issue with cookies.

Comments, questions?  

Thanks,
