Practically, is this going to make any difference? I think the slowest part of processing a result is by far the database activity. "It works as is" is a pretty good reason up against virtually no impact. :-)

Also, I did some quick Googling to see how much faster it is, and it seems like everyone says they're the same or GET is faster.

(If we are going to change the protocol, maybe we should go with SPDY. ;) jk)
