I wrote RPG benchmarks that measure the performance of parsing a JSON
document and mapping a fairly large number of values to an RPG
data-structure array, using 3 different parsers. One parser that I wrote
vs. the YAJL Tree interface vs. the RPG Data-Into / YAJLINTO Interface. I'm
posting links to the RPG source code for each benchmark. The interface that
I wrote performs 25 times faster than the YAJL Tree Interface and 142 Times
faster than the Data-Into / YAJLINTO interface. The Data-Into interface is
not quite an apples-to-apples comparison because it provides no way of
separating the "parsing" vs "data mapping" performance, which is measured
in the other 2 alternatives. Notwithstanding, it's clear that Data-Into
interfaces have a lot of overhead.
