Tried, neither makes much difference. The big hit is Bag operations, which
is why I suggested moving to an OrderedCollection, which basically cut the
time almost in half. The next big hit was to stop doing so many Dictionary
lookups. The way he was doing it, he was doing three times as many lookups
as were required.
I suspect the next big win will come from parsing the key/value pairs
directly from the file.
Later,
Jon
