Hi all

I am running various tests to see what my maximum amount of updates per
second my hardware can cope with and this appears to be greatly affected
by the number of RRA's in a given RRD archive.

What appears to be happening is that increasing the number of RRA's from
2 to 6 has a dramatic effect on how many updates I can undertake per
second. For example I started with


and then moved to


My update speed has fallen by around 60%. Is this what one would expect?

Kind Regards
Richard Burton
