Thanks Tobi,

so do you mean splitting up the rrd into multiple files by putting
only a few (10 to 20) entries into each file (but sill holding 5-10
million rows) would be be better?

Has anybody tried with such a big number of rows?

Or, to put it the other way around:
up to which amounts of data rrdtool has been tested?
