I'm migrating a Nagios installation with 2000 hosts and 6000 services to Shinken, but with just half the hosts and services already configured in Shinken, I'm already experiencing an average latency of over 10 seconds, sometimes even getting to the 40 seconds mark, while Nagios remains under 5 seconds all the time.
I currently have 2 pollers with the following hardware:

CPU: 12 CPU Cores (Xeon E5-2680 @ 2.70GHz)
Memory: 4Gb

The pollers sit between 4 and 6 of Load Average.

Is there anything I can do to try and solve this? I already tried increasing the check interval from 1 minute to 5, with little to no success.
