Hi,

I'm having problems with the performance of the poller.
We have 200 switches and almost 16000 ports included and the poller is having trouble getting them checked in 5 minutes.
With 20 threads it's working with a load of 15. When I add more threads it takes longer to get the data from switches.
With less threads it also doesn't check all switches in 5 minutes.
I'm using new fast hardware.

I've implemented all the performance tuning tips on the observium site.
I also disabled the checking of fbd-table, arp-table and mac-accounting.
When I debug the poller the ports check takes the longest. About 90 % of the total time.
1 switch takes about 8 to 10 seconds now.

Is there a way to speed it up? Maybe I can extend the check cycle time to 10 minutes?
Distributed poller instances?
