We have one Observium server looking at

476 devices (mainly switches, some firewalls, some WAN routers)
3666 ports
8692 sensors

The server has 6 cores (~70% idle, ~3% iowait) and 8 GB memory. We have configured 15 poller threads with max 6 allowed wrapper processes.

The server is struggling to keep the polling cycle below 300 seconds (averaging 376 secs).

Is this workload realistic for one server, and if so where do you suggest we tune? Or do we need to use a distributed setup?
