Just a few hours ago, I have discussed this with a friend of mine.
But when I think of nearly 6000 active service checks on my poor nagios
hardware there might be 3000 service checks with valid performance data
with a avg check interval on 300 seconds. Which means that there might
be around 10 or more performance data per seconds and a fifo is not endless.
But I know that the needed performance data are not as big to overfill
this fifo if you are reading out of it fast enough...
Just a thought.

How many services are you processing this way? Did you run into latencies?
