Hi

Does anyone have an idea of the scalability of m2m2 ?
I mean how many devices / datapoints can one m2m2 instance handle?
Lets assume we have some good server hardware with 24GB RAM etc. and we have 5000 devices that updates 10 datapoints each every 30 minutes.
Would the site still present the historical data quickly after 5 years?
This is 2.400.000 new datapoint updates every 24Hours and approx 876.600.000 every year
I have seen really bad performance on other m2m systems when the database grows beyond a few hundred mega bytes.
The performance with "large" databases is influenced a lot by database design and indexes, search methods, lack of stored procedures etc.

Hi

Is it possible to write a module for m2m2 that changes the user management or is this a part of the core that can not be changed by others than Serotonin ?

The goal for me is illustrated by the following example:
We have 5000 devices submitting data to one m2m2 instance.
The devices are owned by 10 different customers.
The 10 customers should not be able to see the other customers data.
Each of the 10 customers should be able to add new devices them self and manage/add new users who can only see their devices.

I would also like to add other "roles" than administrator and user so that it could be setup what roles can access what reports/pages.
This should be dynamic and the administrator should be able to set it up via GUI.
