zenperfsnmp performance

hi,

im running a fresh zenoss 4.2.5 latest zenup with 1000 devices and the zenperfsnmp is showing Missed_runs.

I have tried changeing the maxparalell and triespercycle but still get missed runs.

I have debugged zenperfsnmp but didnt find anytning wierd. nothing weird in zenhub.log or event.log either.

Runs on a dual xeon (32cores) with 128gb ram and raided ssd enterprise disks.

running on ~2% cpu 75GB free ram .

I notice that making changes, like putting a device interface in down will not get noticed by the system at all or it will take a bit to long time. I will se the traffic graph drop before the status changes. Not sure ifthis is related to the missed runs or not.

Anyone got any tips
