Hello
In kronolith/lib/Scheduler/kronolith.php, the run() function makes two  
big loops (which are very time consuming for a large organization):
- first, for each calendar: retrieve the users concerned.
- second, for each user: set his timezone and then retrieve the alarms  
concerned.

For an organization of many thousands of users, these loops take  
several minutes (> 30 minutes).

How can we improve this process ?
Maybe be storing into a file the users list ?
