A good and seemingly fair comparison of different approaches to using Amazon Web services in PHP, via SOAP and REST.

I’d previously heard Tim O’Reilly’s 85% number (relayed via Jeff Barr), but just learned of another interesting stat in that article; Amazon’s RESTful queries (via GET) are 6x faster than their non-RESTful ones (via POST). That seems high to me, but not having any more details in front of me, it’s hard to dissect why that might be the case. Anyone got the details?
