There are 2D data plots that are hard to do as ASCII art. ;o)
It opened fine for me in Open Office - there was one set of graphs
that looked to be empty, but I couldn't tell if that was OO screwing
up or the way the spreadsheet went out.  But the raw data was
legible and troubling.

Memory copy, network I/O, and disk I/O, by factors ranging from
about 10% to almost 50% - I'd say about 25% on the average.
If this can't be explained by a configuration error, we have a real
problem here, but if that's the case, I'm surprised no one has raised
a red flag earlier.
