I would have assumed the same thing but after numerous tests I just cant see it happening especially not on the Mysql side
After I dropped the DB though things are looking better with a fresh start

It sounds like you probably have some pretty severe I/O bottleneck somewhere.

It's entirely possibly you don't yet have the changes which have the potential to make things "slow" ;)

Are you sure that's running the latest version? The ports table UPDATE seems fairly short.

The continuing saga
It seem that the "processors-state” integration waits for a long time, most other queries / read / writes are being completed in under 5 seconds, as shown below these are “Waiting” for 40+ seconds, these seems to be linked to JOINS in most cases Does anyone have an idea on how to speed these up from a tuning perspective?

the device is reachable via SNMP as shown in a portion of the snmpwalk below
this is where I am seeing the slowing down during the ifindex scanning as previously posted if I poll a radio, Ubiquiti Airfibre/ M5 .

if there anyway of running the poller and but not writing to the DB, I see there is a flag to disable the writing of RRDs, I want to see if the poller performance is the issue, the disk I/O or the DB

We have some /very/ large installs which saw little impact from the changes.

its just very strange how a XEN VM out performs bare metal, it may also be Ubuntu 16.04 as that is on the bare metal server and 15.04 is on the VM

We've changed the way the ports table works, removing memory tables.
It's likely that you now need more mysql resources, since were now writing to an innodb table instead of a memory table.
Odd, really. It didn't seem to have a huge effect on my dev install or some other very large installs.
Perhaps you could investigate mysql performance tuning? :)

Ok if I poll a router / switch / server etc it seems to be ok, a full scan on a 7606 takes around 45 seconds,

The the other thing that had changed is that I was running a slightly older version of Observium on the VM server, still in the 79xx range not the 8003 version

Hi All
I have moved from a VM server to a physical server. as the VM was taking a bit of a pounding, graph dropouts etc The physical server is a dual quad core Xeon, 2.66Ghz with 128GB of RAM and a 32GB ramdisk, and rrdcache I also have 2.5TB or SAS storage in a raid6 config
Will all of this my average poller-wrapper time is around 60 to 70 seconds per device if I manually run an snmpwalk a single device takes around 6 seconds
I have also disabled the ramdisk, rrdcached etc and I am not seeing much of a difference either way
I have around 900 devices and the VM server was way faster, any idea where to start looking for a bottleneck?
