Hmm, typicaly I agree with Stef but here I'm not sure. Speed is derivative of transfered byte count and as such it is dependent on time. Because we can't compute perfect derivative we have to use difference - and it is always computed as average of some time interval (30sec in HTB). So if you use 5s interval in rrd it seems ok for me (it is what i plan to do here). just by opinion :) devik
