That's probably because it is depending on too many variables.

It's just more work, using more resources.

If you divide your data into more than one RRD, but keep updating all DSes, I think there will be slightly more work, not less. I have to admit, there are people on this list with more experience with large scale setups. Let's hope they chime in. Also look through the archives, but I cannot give hints on which keywords to use. _______________________________________________ rrd-users mailing list [email protected] https://lists.oetiker.ch/cgi-bin/listinfo/rrd-users
