If a Zabbix user has permissions set the way there are many groups of hosts which are permitted for them, and the total amount of hosts permitted for the user is set over 1500 (like in my case), the pages open much slower than for the super users (up to 60 seconds). This certainly has to do with the permissions queries and we got this issue after Zabbix 1.8.2 -> 2.0.2 upgrade only. Our critical page is tr_status.php, which should be opened very quickly, but it does not for our regular users.

Is there any recommendation how to fix this manually until is hot fixed in the new releases?
