As you can see the polling time raises drastically. When the device is polled 
from the command line with zenperfsnmp -v10 -d device the execution time is 
below one second. Hence it is not always the same device which polling time is 
rather high. During one run device A takes 0.1 seconds and during another run 
the very same device A takes almost a minute.

The total number is about 400 devices (Cisco switches) and as you can image 
after a timeout zenperfsnmp starts all over again. Any idea why sometimes a 
device takes that long? With that behaviour it is not possible to use the 
performance monitor at all.
