#8147: Calendar slowly loading data
-----------------------+------------------------------------------
 Reporter:  opensaas   |      Owner:  developer
     Type:  defect     |     Status:  new
 Priority:  blocker    |  Milestone:  6.1.0
Component:  vtigercrm  |    Version:  6.0.0
 Severity:  Critical   |   Keywords:  Calendar slowly loading data
-----------------------+------------------------------------------
 Calendar module with a large database of records very performs slowly, to
 load the calendar entries have to wait even a few minutes which is not
 acceptable.

 The problem is how to start a common calendar for 50 users where each of
 them has a 10 - to 20 entries per day, it is not a lot of entries to
 display but very slow loading.
 In the database I have vtiger_activity - 300 K records in vtiger_crmentity
 - 1.1 M records.

 Time to first Loading the calendar (after running the page) about 1-2
 minute.
 Loading time next month, for 50 the users of about 2 - 3 minutes.

 The issue is probably caused by the fact that executes as many database
 queries how many users.
