Hi Peter,
Do you have all the modules enabled?
When I set it to 64 threads the load goes up to 60 but it makes the cycle in 3 minutes. I don't see much network traffic and also not very much disk access.
What load is you system having?
Regards,
Frederik

We are running poller-wrapper with 64 threads, and our 250 devices and 20000 ports is getting polled in about 2 minutes.
We are running this on SSD drives for performance.

2013/10/9 <F.Reenders@utwente.nlmailto:F.Reenders@utwente.nl> 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?
