Hi Johannes,
Your system does not seem to experiance that 'performance death'
others see ... figures with that much ram ... you may want to try
the new version of the script I am attaching ... it tries harder to
figure where the limits lie ...

as comparisons go I guess we need to define some 'benchmark'

what about the following: How many rrdfiles can your maintain when
you run at a 1s interval ... how many at a 10s interval and how
many at a 60s interval ...

in your list below my guess is that your system would be able to
keep 2000 rrds up todate ina 1s interval ...

cheers
tobi
