What are the user limits? + 2

[ojoy]

I have been looking for a CMS for some time and some how fell into Chamilo.

How far can the platform grow?

Is the two hundred page English version of the manual used in Brussels March of 2012 available (as in for sale) ?

Why are you running on Drupal?

I would like to help the SaaS angle of the game.

Chamilo 1.8.7 or its close predecessors have been tested without major influence on the server load with:

* 800 simultaneously connected users (in a 240 seconds timeframe)
* 32,000 courses
* 229,000 registered users
* 35,000 connexions per day

Current http://campus.chamilo.org has ...

* 19,600 registered users
* 300 simultaneously connnected users (120 seconds timeframe)
* 3,500 courses
* ... and runs on ...
* 2 x Intel Xeon Dual-Core 5130
* 2GB RAM
* 250GB SATA HDD
* X7DBN Motherboard
* 5TB / month bandwidth

The videoconference tool has been tested on a virtual machine with 300MB of RAM with 20 people connected simultaneously and has shown no defect or excessive load. It has also be tested with up to 45 users in the same institution and has proven to be a bit slow and add audio delay. This was mostly due to testing it with so many computers in the same network, making the work difficult for the streaming server in terms of address translations.

It is also estimated that the practical limits for a quad-core processor with 8GB of RAM and a ZFS-type file system (given small interface improvements) would be:

* 1 000 000 users registered
* 5000 simultaneously connected users (with a time window of 60 seconds)
* 32 000 courses
* millions of sessions

Thank you, the server and machine side is good, BUT (there's always a but somewhere) what about the connection side (T1 backbone, plain ADSL, ISDN, POTS ???)
You can have a huge machine, if using a single modem, you'll accept only 1 connection at a time .

It all depends on the amount of data you're going to transfer there. For the Chamilo free campus, we have a 3Mbit line which is enough to hold 5-600 simultaneous users but the content is limited to documents. All streaming is handled by YouTube and the likes.
