Do you think
it be more efficient to scan the string once and grab the
field values as I get to each field marker?
Yes.
Yes, the machine is cpu-bound.

I have had good results with YourKit. Simple to set up and a nice
output that shows where the time is spent. I have used to to

I'm not sure how to "Split it on the &, put it into a suitably keyed
