Hi guys,

What's the limit of concurrent users in a web app server full
version? I've a project in folder which will have about a thounsand of
concurrent users.

What recomendations can you give me? I mean to succefully
accomplish this requirement and not to sink close to the other side.

Thanks!

Hi Ruben

there is unfortunately not simple answer to that question...

It all depends of the type of site (classic/awp), of the type of server
you are using (speed, memory, disks, etc) and most of all of your coding
and your application...

If your site is classic, then each session is using some memory and you
can guesstimate the total RAM needed (knowing that depending on your
app, this amount may vary tremendously, because of the actives queries,
by example)

Now, a few years back, Microsoft was saying that IIS limit was 800
SIMULTANEOUS users (which isn't the same as saying 800 webdev sessions
open, as not everybody is doing something at the same time, hence NOT
simultaneous)... Clearly, the current limit has to be higher than that,
but again, concurrent users does not means simultaneous users...

The only benchmark I can give you is that at the time (webdev 11) we
were working on a big classic project with several hundreds users
working on the site 8 hours a day. We planned the system with two
web/webdev servers on a load balancer and a third one hosting the HFCS
DB... And this was a HUGE overkill when we went on to the full
deployment phase

Hope this helps, best regards
