It is my experience now that where performance is concerned, it is important to move as quickly as possible from a collection of JsonValue to a collection of JsonObject.
What you escape in that way is both any-casts and any-calls.
If I have an array of JsonValue, I iterate over it with asa JsonObject within
{with-compiler-directives allow-implicit-any-casts? = true do
}
to create a collection of type JsonObject.
The difference in performance has been dramatic: 10 seconds for several hundred records versus 1+ second - so about an order of magnitude improvement.
I am only using JSON because I have made some files available in that format.
My next efforts will be with using Curl value classes for multiple name-value associations of type String.
UPDATE: a comparison of the JSON to the Curl data is posted at http://lcurlr.blogspot.ca/2012/05/curl-versus-json.html
