what's faster on iPhone? XML pList or JSON?

Assuming both XML plist and JSON are delivered over http, gzipped, which one will be processed faster on an iPhone?

A co-worker and I did some rudimentary benchmarks recently to test which was faster for an application we were writing. We tested this JSON framework, and the NSXML parser as well as a TreeNode parser we found in an Objective-C book. Here is the note I sent to the other developers on our team:

The benchmark tested how each library handled getting the filename and path
of 100 assets, 100 times each (for a total count of 10,000 runs per library).
The results are below:

Method    Average(s)    Total(s)
TreeNode  0.307475      30.747493
NSXML     0.483778      48.377843
JSON      0.233179      23.317870

In the "Building a Server-Driven User Experience" session of WwDC, an Apple developer stated that PLIST was preferred for being faster and easier to use.

It depends on the data that is delivered and the way it is parsed, but they should both be similar in speed. You should just choose the one that is easier for you to develop a parser and then fine tune the parser.
