Denis,

the necessary system architecture heavily depends on the processes and data being processed. The number of users is only one factor in the math.

We were responsible for ecommerce systems with thousands of users, traffic coming from TV spots in a short time period etc. running on non-clustered servers (landscape of webserver, application server (OFBiz) and database server with failover).

OFBiz has excellent caching mechanisms and can be run on (relatively) small hardware configurations.

To size this, you have to know your data, processes, long running threads and technical configuration (JVM, memory usage, garbage collection etc.).

It can be complex but be assured: OFBiz can handle huge amounts of simultaneous users and lots of data efficiently.

Best regards,

Hello Steve,

It's a kubernetes cluster, so I haven't exactly the hardware
configuration. But the platform have 10 instances of vserver with min 8Go
and 80% allowed of cpu ressource

Hi Nicolas,
Could you kindly give an indication of the resources (and additional
tweaks)  you have deployed to support the 1000+ users
Regards

:) Yes and more than 1000 from our side.

Hi Nicolas,
I understand that theoretically it is possible. But are there real
cases
with 1000+ users?

Hello Denis,

Depends to your system architecture and process manage by OFBiz, you
can
have more than 1000 users simultaneous with a good charge sharing or
10
with difficulty if you haven't enough resources

Hi all,
Are there any measurements, how many users can work in parallel in
a real
production system in  OFBiz ?
At least approximately - is it 10-20 concurrent users or 500+ ?

BR,
Denis
