Hey ! Watch who are you calling dummy, dummy. :-)

OK, understood.

And I noticed you mentioned 0.14 seconds on a 100MB file (I first thought 
you said 14 sec).   Here a repeated search on just a 5MB file gave me 
between 2 and 5 results a second, or between 200 and 500 mSec.     I would 
have expected that with a much larger datastring it would become a multiple 
of that.

Other than viewing an rain probability image or two ? No, not really. Sorry.
