Far out; I get the same results you do, using my old version of rrdtool!
Graphing val2 from your CDEF works much better than graphing val1 from
the DEF. It runs in virtually the same length of time as does a graph
of one of the "fast" columns. This seems to be a fine workaround, once
I adjust my Y-axis label. I like graphing in MB (maybe even GB) better
than graphing in KB anyway. Thanks!!!
What is your take on this?
