Hello,

We migrated our zabbix to your newest Zabbix version. After that the performance is very bad.

Status of Zabbix:

For example, there is a problem with some server, but we recieve notification only after 15 min.

Our server load is ok:
DB:
14:21:05 up 53 days, 24 min, 1 user, load average: 5.22, 4.99, 4.86

Zabbix server:
15:08:19 up 18 days, 5:21, 2 users, load average: 1.40, 0.93, 0.74

What could be the problem?
