Processing speed, not compression

In Will EXI Mean XML Everywhere?:

“It is unlike data compression, which has overhead associated with it,” explained Schneider, whose day job is as CTO of AgileDelta, which makes XML parsers. “XML is verbose and inefficient; [EXI] streamlines all of [the processing] with the minimal size representation of XML information possible,” said Schneider. “We want to make it competitive with hand-optimized binary formats.”

“When W3C tested EXI, it was, on average, 12 to 14 times faster than processing normal XML.”

I hope people will finally stop mixing up compression and efficient processing.

Quoting myself: ;)

And, as the binary format should be the most efficient way to represent that data, it really is the leanest ad-hoc binary format.

and

Only minor improvements should be able to be gained with further ad hoc binary formats, as the qualitative improvement in reducing the parsing complexity is already achieved. Thus, there should be no room for more efficient ad hoc format […].
