NetCDF-4 AR-4 Performance Data With One Time Series

Another concern that Russ and Dennis and I had was that by taking 5 time series, we were involving the cache too much. Might the data not be already pre-loaded after the first time series is retrieved?

So in this run I do one one time series read. This is all on the 3D precip flux data that Gary gave us.

Sorry about the alignment of the columns, but they show up fine for me in emacs. Obviously this fancy web technology is only a few years away from doing what emacs could do in 1981...
