Performance of std.json

[Sean Kelly via Digitalmars-d]

The vibe.d parser is better, but it still creates a DOM-style
tree of objects, which isn't acceptable in some circumstances.  I
posted a performance comparison of the JSON parser I created for
work use with std.json a while back, and mine is almost 100x
faster than std.json in a simple test and allocates zero memory
to boot:

I haven't tried it vs. the vibe.d parser, but I suspect it will
still beat it by an order of magnitude or more because of the not
allocating thing.

I've said this a bunch of times, but what I want to see is a
SAX-style parser as the bottom layer with an optional DOM-style
parser built on top of it.  Then people who want the tree
generated can get it, and people who want performance or don't
want allocations can get that too.  I'm starting to wonder if I
should just try and get permission from work to open source my
parser so I can submit it.  Parsing JSON really isn't terribly
difficult though.  It shouldn't take more than a few days for one
of the more parser-oriented people here to produce something
comparable.
