Hello, td_bolin!
The gathering interval will not happen simultaneously. Only in the case where you have configuret a lot of pollers in zabbix server.

For further debuging please make sure that zabbix server has assigned "Template App Zabbix Server" and take a look on graphs:
* Zabbix server: Zabbix cache usage, % free (12h)
* Zabbix server: Zabbix internal process busy % (12h)
* Zabbix server: Zabbix data gathering process busy % (12h)

Please share some output!

P.S. There is one thing which is calculated hourly (hardcoded) and that is: trend calculation.
