[rrd-users] Re: Performace: update v/s updatev

[Tobias Oetiker]

Hi Praveen,

there should not be much of a difference, since the values
displayed do not get 'read' from the RRAs. rrdtool knows the values
because it writes them to the RRAs. The only difference is wether
it tells you about it or not ...

cheers
