Does it depend on the hardware or OS?
How many users can be handled in reality?

Tnx,

Frank

It depends entirely on the platform and infrastructure.  OpenACS supports clusters of webserver front-ends to the database (to some degree at least), so you could have a half-dozen dual-processor x86 Linux boxes with a couple GB each hooked up to a massive Solaris Oracle server and handle a huge load.

It is more realistic to ask:

1. How many users can I expect to support on this specific platform/infrastructure

2. What do I need to support N users or hits-per-second or ...

Which system would you recommend for 1500 concurrent users (i.e. chatters at the same time)?

if you have 1500 people in chat at the same time you'll want a real (i.e. something that supports persistent connections unlike http) chat solution, not the hokey store-messages-in-the-database stuff that acs does out of the box.

Not sure whether this is the original source of this document, but here's a link.
